Dynamic performance analysis of transcritical power cycle with preheater and regenerator using CO2-based binary zeotropic mixtures

The CO2 transcritical Rankine cycle is considered as an ideal solution in the application of waste heat recovery due to its safety, environmental friendliness and compactness characteristics. In this work, for the heat recovery from internal combustion engine, a dynamic model of an improved CO2 transcritical Rankine cycle system containing both a preheater and regenerator with CO2-based binary zeotropic mixtures as working fluid is developed. The performance of CO2 transcritical power cycle with preheater and regenerator was compared and analyzed for mixture working fluids with different proportions under the disturbance of heat source conditions and system input parameters, which can provide references for system control strategy to ensure efficient and stable operating conditions when selecting control variables. The results show that there is a certain pump speed to obtain the optimal value of the net output work and thermal efficiency of the system. And the net output power and thermal efficiency of system with CO2-based binary zeotropic mixtures at optimum point are higher 6. 34 kW and 2.19% respectively than pure CO2 as working fluid by adjusting pump speed.

Sound absorption of space-coiled metamaterials with soft walls

Integrating soft components into acoustic metamaterials is an extremely promising way to enhance their adjustability and reconfigurability. Herein, we report a type of space-coiled metamaterials using soft walls to construct internal channels, denoted as soft-wall space-coiled metamaterials (SSM), exhibiting superior sound absorption performance at low frequencies. The physical mechanism of the SSM is revealed through finite element simulations and sound impedance tube-based experiments. It is demonstrated that the exceptional sound absorption of the SSM originates from the strong coupling effect between the friction-like dissipation along the internal channel and the deformation-like dissipation in the soft wall. The experimental results show that the fabricated SSM sample with a subwavelength thickness (<1/25 wavelength) features near-perfect sound absorption (reaching 0.97 at 615 Hz) and a broad half-power bandwidth (1.6 times that of the rigid-wall space-coiled metamaterials sample with the same geometric dimensions). Moreover, the SSM has excellent sound absorption performance under oblique incidence even when the incident elevation angle reaches 75°. This work may bring inspiration for developing soft-components-integrated acoustic metamaterials with compact, adjustable, and reconfigurable characteristics.

Effect of calcined clay on the improvement of compaction, swell and microstructural characteristics of expansive soil

Expansive soil is problematic soil because its alternate swell shrink behaviour depends on the presence of water. Soil stabilization technique was widely adopted to alter the characteristics of the expansive soil which is suitable for construction. Among the various soil stabilization techniques, chemical stabilization was found to be more suitable method of sustainable stabilizing the soil due to its effective and timely reaction with the chemical compound. Calcined form of clay material is used as an admixture to study the effects on the improvement of soil properties. Calcined Clay (CC) is added into the virgin soil with different percentages of 2%,4%,6%,8% and 10% under varying 1,3,7,14,28 and 60 days of curing by conducting experiments such as standard proctor test, Free Swell test to analyse the compaction characteristics and swelling behaviour of the soil. In addition to that the X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM) on virgin and treated soil were studied by varying 2% incremental of CC up to 10% at 28 days of curing. From the test results it shows the variation in the compaction characteristics by rising in Maximum Dry Density (MDD) and reduction in Optimum Moisture Content (OMC) that merges at 8% as an optimum to develop the soil behaviour and from the free swell test, it was found that the Free Swell Index (FSI) of the soil decrease from 210 to 80 at 10% calcined clay added soil and the Mineralogical studies also show the variation in the compounds. Thus, this naturally available calcined clay was used to improve the soil Compaction and swell characteristics that influences the reduction in deformation and increase in shear strength of soil which helped to minimize the environmental problem as well as one of the effective admixtures to improve the expansive soil characteristics.

Compaction Characteristics of Organo-silane Treated Soils

Abstract The extent to which hydrophobic soils can be used in geotechnical engineering practice depends upon a commensurately increased understanding of how fundamental relationships apply in hydrophobic systems, such as moisture-density. This research is to determine the compaction characteristics of organo-silane (OS) treated soils using conventional geotechnical laboratory equipment. The intrinsic difficulty in lubricating hydrophobic soils, which would allow for rearrangement of particles and subsequent compaction, arises from their inherent low surface energy. This work describes a method for compacting OS treated soils that leverages the necessary conditions such as reaction time and drying conditions for achieving hydrophobicity. Procedural steps for compacting OS treated soils are detailed by making use of a water-soluble hydrophobizing agent added to a fine-grained soil. Based on the critical dosage ratio of 1:100 (hydrophobizing agent: soil) identified, a molding water content is defined constituting of a fraction of the hydrophobizing agent. Soil water content and dry density curves are developed using the standard Proctor and Harvard miniature to contrast the resulting effect of OS. Compared to the untreated soil, a decrease in optimum water content was observed with the OS treated soil regardless of compaction technique used. For the standard Proctor test, a decrease in optimum water content from 12.0 to 9.2 % was observed, whereas compaction with the Harvard miniature showed a marginal decrease from 9.3 to 9.0 %. With the untreated soil, a relatively larger maximum dry density (2.17 g/cm3) was obtained with the standard Proctor compared to the Harvard miniature (2.05 g/cm3). The protocol defined to compact OS treated soils has shown to induce hydrophobicity spatially within the sample depth. These results suggest that engineered water repellency can be implemented in so far as treatment and compaction are largely synchronous and prior to reaction and hydrophobization.

Examination of Halfway Substitution of Cement M20 Concrete with Silica Rage and Quartz Sand in Fine Total

The misuse of waste material has developed into another draw because of the significance of consciousness and unpleasant feelings. A by-product of the refinement of silicon and ferrosilicon is silica fume (SF). The design and production of reinforced concrete has seen remarkable success with silica fume. One of the most crucial elements of the commercial viability of modern work has been the short-term usage of Silica Rage (SR), as well as the commercial manufacturing of SF-regulated natural flowing stone residues in cohesive form, which generates early and high pressure. Ferocity Stone. High seniority is beneficial for secure and robust data. Experts and experts were compelled to employ different techniques due to the heritage's rarity and underlying concerns about the collection's quality. This particular characteristic advises employing quartz sand as an environmentally beneficial alternative to fine sand. An excellent technique to increase weather resistance is to use quartz sand in place of regular sand. The performance of both new and reconditioned concrete is examined in this article along with the qualities of quartz sand and smouldering silica. We are exploring the detrimental effects of concrete constructed of SF and semi-substitute cement in this study. The value after use will consider the concrete's new solidification characteristics.

Key Words: quartz sand, silica fume, compaction characteristics, surface ductility, and bendability

Effect of nano∖micro‐textures on the enhancement of tool wear resistance in green ceramics processing

AbstractThe processing of green ceramics aims to obtain parts with complex shapes and good surface quality. This paper prepared tools with micro/nano‐textured flank face by femtosecond laser to improve the cutting performance in processing of Al2O3 green ceramics. The wear resistance of cutting tools and characteristics of machined compacts are analyzed. Results shows that textures can improve the wear resistance of cutting tools and surface quality of green ceramics. Micro/nano‐textured tools own the best cutting performance, the improvement rate of wear resistance and surface roughness can reach 28.5% and 25% respectively. The reasonable mechanisms are explained by the storage of powder chips and the derivative‐cutting phenomenon by textures. The derivative‐cutting behavior can prevent cutting tool from severe abrasive wear by hard phase particles. The storage function prevents the powder chips from scratching the unworn surface of cutting tools, and the additional scratching of the machined surface by the hard phase particles is reduced. The two functions contribute to the improvement of cutting performance of micro/nano‐textured tools.

Laboratory Testing and Analysis of Clay Soil Stabilization Using Waste Marble Powder

Soil stabilization is a critical step in numerous engineering projects, preventing soil erosion, increasing soil strength, and reducing the risk of subsidence. Due to its inexpensive cost and potential environmental benefits, waste materials, such as waste marble powder (WMP), have been used as additives for soil stabilization in recent years. This study investigates waste marble powder’s effects on unconfined compressive strength (UCS) and clayey soil’s ultrasonic pulse velocity (UPV) at different water contents and curing times, and artificial neural networks (ANNs) are also used to predict the UCS and UPV values based on three input variables (percentage of waste marble dust, curing time, and moisture content). Geo-engineering experiments (Atterberg limits, compaction characteristics, specific gravity, UCS, and UPV) and analytical methods (ANNs) are used. The study results indicate that the soil is high-plasticity clay (CH) using the Unified Soil Classification System (USCS), and adding waste marble powder (WMP) can significantly improve the UCS and UPV of clay soils, especially at optimal water content, curing times of 28 days, and 60% WMP. It is found that the ANN models accurately predict the UCS and UPV values with high correlation coefficients approaching 1. In addition, this study shows that the optimum water content and curing time for stabilized clay soils depend on the grade and amount of waste marble powder utilized. Overall, the study demonstrates the potential of waste marble dust as a soil stabilization additive and the usefulness of ANNs in predicting UCS and UPV values. This study’s results are relevant to engineers and researchers working on soil stabilization projects, such as foundations and backfills. They can contribute to the development of sustainable and cost-effective soil stabilization solutions.

Influence of compactive effort on the strength characteristics of lime treated laterite soil mixed with untreated textile effluent

Industrial waste generated is a major contributor of total waste worldwide. The proper mechanism for management of these waste needs to be established, especially in developing countries. Therefore, this paper attempts to evaluate the influence of compactive effort on the strength characteristics of lime treated laterite soil mixed with untreated textile effluent. The study was carried out on the index properties, unconfined compressive strength (UCS) and California bearing ratio (CBR) in accordance with the procedures specified by BS 1377 (2) 1990, 1924 (2) and Nigeria General Specifications. Three compactive efforts namely; British Standard light (BSL), West African Standard (WAS) and British Standard Heavy (BSH) were used for the strength characteristics. The findings of the study showed that an increase in the values of lime-TE results in general increase in the strength tests. An improvement in the UCS for 7, 14 and 28days curing period was recorded at peak values of 1531.91, 2199.29 and 2560.48kN/m2 for BSL, WAS and BSH at soil-lime-TE of 4% lime/75% TE, 8% lime/75% TE and 8% lime/50% TE respectively. For the CBR (soaked), the peak values were recorded at 49.70, 71.13 and 97.25% for BSL, WAS and BSH at soil-lime-TE of 6% lime/50% TE, 6% lime/50% TE and 8% lime/50% TE respectively. Considering the resistance to loss in strength, the values were also peaked at 71.77, 81.74 and 60.63kN/m2 at mix ratios of 8% lime/100% TE, 6% lime/75% TE and 8% lime/25% TE respectively. On the bases of these test results, it can be concluded that the utilization of untreated Textile Effluent positively increased the strength characteristics of the lime treated soil, reduced environmental pollution and save construction cost.

Empirical Equations Expressing the Effects of Measured Suction on the Compaction Curve for Sandy Soils Varying Fines Content

To effectively apply various soil types for embankments, understanding their compaction characteristics is crucial. One crucial factor affecting compaction is suction, which plays a significant role as it is typically performed under unsaturated conditions. Suction varies with soil density, water content, and fines content. This study directly measures suction after soil compaction using the triaxial apparatus, unlike the Soil water characteristic curve (SWCC), assessing its impact on compaction characteristics. Immediate suction measurement after compaction provides apparent suction, resembling on-site conditions with open pore air pressure. Comparing SWCC with apparent suction at each compacted state reveals that suction and air entry value increase with initial density, positively impacting compaction. Notably, apparent suction aligns better with wetting process suction from the SWCC due to added water during specimen preparation. Empirical equations are derived to obtain suction contours across various density and saturation ranges, aiding in understanding suction variations on the compaction curve. Even slight variations in saturation causes noticeable changes in apparent suction during higher compaction efforts, affecting soil compaction characteristics. Therefore, the precise control of saturation control is needed to achieve desired properties of compacted soil, especially at higher compaction efforts and with various soil types. This understanding significantly impacts the mechanical behavior of unsaturated soils.

Study on compaction characteristics and mechanical performance deterioration of large stone porous asphalt mixes

Large stone porous asphalt mixes (LSPM) have advantages in promoting pavement performance, including cracking resistance, rutting resistance, and moisture susceptibility. Engineering practice demonstrates that performance degradation is crucial and has an impact on the durability and service life of asphalt pavement. Therefore, this paper aims at investigating the damage characteristics of LSPM as well as proposing the corresponding control methods. Firstly, a simulation device is designed to carry out the temperature cooling testing of LSPM in the laboratory. Then, the variation of air void contents in LSPM was analyzed with different testing temperatures, loading times, and freeze–thaw cycles. LSPM macro-mechanical strengths and cracking resistance were measured during freeze–thaw cycles. The outcome demonstrates that different sections cool at various rates and for varying lengths of time. The effective compaction time and compactness are directly related to the ambient temperature. Paving at medium and high temperatures is an efficient way to increase the compactness of LSPM. The testing temperature, loading time, and freeze–thaw cycles have significant influences on the change of air void contents, while the influence of load strength is low. The penetration shear strength decreases as the number of freeze–thaw cycles increases, and the change trend gradually decreases. Freeze-thaw cycles will lessen the anti-cracking performance of LSPM. Strictly regulating construction parameters, air void content, and drainage conditions could increase the LSPM asphalt pavement's durability and service life. The change in pore structure composition is the primary factor influencing the damage performance of LSPM.

Tailoring of Compaction Parameters of the Vibratory Table and Vibratory Hammer for Roller Compacted Concrete Pavements to Resemble Field Properties

Previous studies have indicated that roller compacted concrete pavement may demonstrate significant variations in field behavior compared to laboratory specimens. This discrepancy can be attributed to the dissimilarities in compaction efforts between laboratory and field conditions, wherein the laboratory efforts fail to emulate the field compaction. Thus, in the present study, efforts have been made to optimize the compaction parameters, especially the number of layers of widely employed compaction methods, viz, the vibratory hammer (VH) and vibratory table (VT). A field slab was constructed using a duplex roller to provide a target value for the optimization process. Parameters such as packing density, fresh density, mechanical properties, viz, compressive, split tensile, and flexural strength, and porosity were considered for the tailoring process. Fresh density results showed that VT and VH-compacted specimens with ASTM parameters were loosely (−1.1%) and densely compacted (+5%), respectively, compared with field specimens (FSs). Therefore, to determine the optimal compaction parameters, the number of layers increased to five in the VT method and decreased to one in the VH method. Among different compaction layers, only the specimen fabricated with four layers and one layer in the VT and VH methods, respectively, could closely resemble the fresh, mechanical, and porosity of FSs. In addition, a new compaction procedure for fabricating prismatic specimens is developed for the VH and VT methods based on the compaction energy and packing density approaches.

Experimental study on stabilization of clayey soil using agricultural and industrial waste

The purpose of this experimental study is intended to explore if SCBA (Sugarcane Bagasse Ash and Marble Dust) may help clayey soil stabilize and hence to overcome environmental pollution. BA (Bagasse Ash) is the waste produced by the sugar factory after the processing of sugarcane. Factories dispose of the BA in the landfills which affect the environment, one of the reasons to do this experiment is to make use of this waste product for a sustainable environment. At the time of marble manufacturing, marble dust is produced. The soil around a building's foundation plays an important influence on its stability. As a result, the engineer should have a complete understanding of the components that influence soil behaviour and can be affected by the soil stabilization process. The soil is treated with bagasse ash and a partial replacement of marble dust (13 percent, 17 percent, and 21 percent) (10 percent, 12 percent, and 14 percent). In this study, a large number of specimens were made, and then the test specimens were analyzed for compaction characteristics and CBR. It was discovered that an increase in MD (Marble Dust) and BA increased the compaction and CBR characteristics to a certain extent.

Experimental investigation on geopolymer-stabilized expansive soil

Expansive soils pose serious issues because to their insufficient bearing capacity and trivial deformation characteristics. These soils must be made suitable for engineering projects by soil improvement in the present scenario due to non availability of appropriate sites. The addition of industrial by products to locally expansive soils has gained popularity due to low carbon emissions and low incurring cost for improving soil properties. At present excellent bonding properties of geopolymers have been recognised as superior sustainable Alkali activated binders for soil stabilization. The paper discusses the effect of addition of Ground Granulated Blast furnace Slag(GGBS) with Geopolymer in combination to a selected high expansive nature soil properties varying GGBS proportions from 5% to 20% and Geopolymer solution from 0.6 Molarity to 1.0 Molarity (0.6 M to 1.0 M). Series of tests were conducted for Plasticity characteristics, Compaction characteristics, Unconfined Compressive strength test and Consolidation characteristics. From the test results optimum amount of GGBS is 10% and Geopolymer is 1.0 M, at this combination the Unconfined Compressive strength was found to enhance by 238% and swelling pressure decreased by 90% and Compression index reduced by 58%.

An Experimental Investigation on Influence of Mixing and Compaction Temperature on Air Voids in Bituminous Mix

Abstract: The air void content and long-term performance of pavements are significantly impacted by the mixing and compaction temperature of bituminous mixtures, leading to potential failures such as premature aging, reduced durability, and issues like fatigue life, raveling, rutting, and vertical consolidation in Hot Mix Asphalt (HMA) pavements. To achieve optimal production and placement of HMA, it is crucial to carefully consider the mixing and compaction temperatures of the binder (bitumen) used. Notably, these temperatures vary based on the grade and origin of the bitumen, as different sources exhibit distinct properties affecting the mixing and compaction characteristics. Selecting an appropriate mixing and compaction temperature is vital to ensure effective aggregate coating and achieve the desired density. This experimental study aims to determine a reliable method for estimating the mixing and compaction temperatures for both modified and unmodified bitumen, thereby enhancing the overall performance and longevity of asphalt pavements.

Study on compaction characteristics and discrete element simulation for rubber particle-loess mixed soil

The rapid surge in traffic volume in China has resulted in a substantial accumulation of waste tires. By harnessing the lightweight and deformable characteristics of tire rubber particles, they are combined with soil to form rubber particle-loess mixed soil, which is progressively being embraced in civil engineering as a pivotal approach towards attaining green and sustainable development. In this study, waste tire rubber particles were integrated into loess to generate rubber particle-loess mixed soil, and compaction tests were conducted to investigate its compaction characteristics. Furthermore, PFC3D (Particle Flow Code 3D) was utilized for simulating the bearing ratio test of rubber particle-loess mixed soil, thereby validating the feasibility of numerical simulation for calculating CBR (California bearing ratio) values and exploring the relationship between micromechanical characteristics and macroscopic characteristics of such mixtures. The findings indicate that the maximum dry density of rubber particle-loess mixed soil significantly decreases with an increasing content of rubber particles. The utilization of PFC3D discrete element software proves efficacious in examining the bearing capacity of this mixture. Notably, when 20 mesh rubber particles constitute 20% by volume, the CBR value reaches its pinnacle and exhibits optimal bearing capacity. From a micromechanical perspective, the variation in internal porosity of rubber particle-loess mixed soil is positively associated with changes in macroscopic optimal water content, and negatively associated with changes in macroscopic CBR value. incorporating rubber particles enhances resistance against external forces while diminishing deformation within loess. This study provides a guidance for the efficient utilization of waste tires and the improvement of loess’s characteristics.

Correlation between one-dimensional consolidation coefficients and different basalt fiber lengths and RHA-cement contents in fiber-reinforced stabilized expansive soils

Recently, environmentally friendly soil reinforcement and stabilization techniques, used to reconstitute weak expansive soils, are on the rise, calling for an in-depth analysis of the consolidation projections on the engineering structures built on them. This study investigated one-dimensional consolidation coefficients by conducting a series of oedometer tests on expansive soils reinforced with basalt fibers of different lengths, stabilized with rice husk ash (RHA) as an environmentally friendly cement-reducing aggregate, and nominal dosages of cement in specified combinations. The correlation between the coefficients of consolidation (cv), volume change (mv), and permeability (k) and different basalt fiber lengths and RHA-cement contents in ultimate soil composite material was quantified using equations and graphical forms. Furthermore, scanning electron microscopic imagery (SEM) was conducted to examine the structural modifications within the reinforced and stabilized soil specimens upon one-dimensional consolidation. The results showed that basalt fiber-reinforced specimens, comprised of 5% RHA and 3% cement mixtures, showed the lowest one-dimensional consolidation coefficients with a notably greater reduction at high-stress states than the control specimen. Additionally, the coefficients of volume change (mv) and permeability (k) decreased with the increased compactive effort, with a clear and significant reduction in the basalt fiber-reinforced stabilized soil composites. This study also proposed the best material combination scheme and analytical equations for evaluating the cv, mv, and k considering basalt fiber lengths at different pressure levels. The ultimate soil composites had superior properties, and thus, can be used as fill or subbase material for such engineering structures as embankments, pavements, and foundations.

Bioremediation of Oil-contaminated Sand

The energy demand is set to grow very rapidly and the potential demand for oil around the world is at its highest level. Apart from indigenous oil sources, crude oil is imported by water transportation to fulfill local demand. The occurrence of oil leakage during drilling and transportation in pipelines is a major concern. As a result of this, soil is getting polluted and its geotechnical properties are altered. In this study, the effect of engine oil and diesel contamination on the geotechnical parameters of sea sand has been studied. Further, to enhance the properties of oil-contaminated sand, the bioremediation method was adopted. Sea sand from Ganagalla Peta beach, Andhra Pradesh state, India was taken up for the study. In the laboratory, 4%, 8%, 12% and 16% of engine oil and diesel were used to artificially contaminate the sea sand and geotechnical parameters; namely, compaction, shear strength and permeability, were studied for oil-contaminated sand and compared with those of virgin sea sand. In the next stage, bioremediation of engine oil-and diesel-contaminated sand was carried out to improve the geotechnical properties. It has been found that the geotechnical properties had improved after three days of bioremediation. Fourier transform infrared spectroscopy (FTIR) analysis showed that the contaminated sand is of a lipopeptide nature and showed the presence of carboxyl groups, whereas the IR absorption pattern of the treated sand matches with N-Methyl-N-Vinyl Acetamide. KEYWORDS: Engine-oil contamination, Diesel contamination, Bioremediation, Bacillus subtilis, Geotechnical properties, Compaction characteristics, Shear-strength characteristics, Permeability, FTIR analysis.

A novel method for determining the particle breakage contribution of high-speed railway graded aggregate and its application in vibratory compaction

The essence of vibratory compaction of high-speed railway graded aggregate (HRGA) materials lies in both internal particle rearrangement and breakage. However, there is a research gap on the level of particle rearrangement and breakage effects on the vibratory compaction characteristics. A novel index, the breakage contribution rate Cb, was proposed to quantify the contribution level of particle breakage to vibratory compaction characteristics based on theoretical derivation. Additionally, the relationship between the gradation, maximum dry density (MDD) and Cb was established using a high-performance machine learning (ML) model. Finally, the impact of Cb on vibratory compaction characteristics under different compaction conditions, including vibration parameters, container size, and sample thickness, was explored through laboratory vibratory compaction tests (LVCTs). The results show that the Cb is better predicted by the PSO-ANN-ML model (the comprehensive evaluation index in the testing set is 4.028). Under different compaction conditions, Cb has a significant important effect on determining the actual dry density (ADD). When Cb> 8.8%, it may lead to over-compaction, which has a negative effect on the overall quality of the compacted structure. Based on the analysis of Cb and ADD, it is recommended that the vibratory frequency should be set to the inherent frequency of the sample, while the ratio of excitation force to static load should be controlled at 1.8. The ratio of the container diameter and the sample thickness to the maximum particle size of the sample should be controlled at 4.4 and 3.5, respectively. The breakage contribution rate index proposed in the study has significant implications for the control of compaction quality and the understanding of the compaction mechanism.

Coupled Effect of Cementation Solution, Curing Period, Molding Water Content, and Compactive Effort on Strength Performance of Biotreated Lateritic Soil for Municipal Solid Waste Containment Application

Microbial-induced calcite precipitation (MICP) is a soil improvement technique that has shown great potential in several geotechnical applications in the previous decade. Some factors that led to the improved strength included cementation concentration. The combined influence of these factors with the cementation reagent was paramount to the calcite precipitation level within soil grain contact of a biotreated compacted fine-grained soil. In this study, the influence of the concentration of the cementation solution [(CCS) 0.25, 0.5, 0.75 and 1.00 M], curing time [(CT) 24 h, 3, 7, 14, and 28 days], and molding water content [MWC (9.8%–19.6%)] of biomediated lateritic soil or lateritic soil that was bioinfused with ureolytic microbes at different suspension densities (cells/mL) and compacted with Reduced British Standard Light (RBSL), British Standard Light (BSL), West African Standard (WAS), and British Standard Heavy (BSH) energy, respectively, were evaluated. In addition, this study focused on unconfined compressive strength (UCS). The results showed an increased UCS with the corresponding average calcite content up to peak values at 0.5 M cementation concentration for the five considered bacterial cells/mL. In addition, the results showed a linear relationship between UCS and average calcite content for the CCS that were considered. The effect of the curing period on UCS was marginal within individual cementation concentrations regardless of bacterial cells/mL. The UCS of the specimen that contained the optimal 0.5 M cementation concentration increased with higher bacterial cells/mL but decreased with the MWC. The qualitative microanalysis that used scanning electron microscope (SEM) and X-ray diffraction (XRD) analyses that evaluated the untreated and biotreated specimens showed the formation of calcite, which increased the soil strength by blocking the soil pores through grain–grain contacts.
