Selection of sustainable construction material from recycled waste plastics by q-rung orthopair fuzzy SWARA-MABAC approach

Recycling of waste plastics and agro-industrial waste for the development of sustainable polymeric composites is recognized as a viable approach to overcome the detrimental environmental effects of plastics waste. Despite of immense potential of sustainable composites in the Circular Economy (CE), its implementation is still insignificant due to the lack of an effective material selection approach. The existence of several influencing aspects in the process of material selection considers it a multi-criteria decision making (MCDM) problem. In the present work, an Aggregation Operator (AO) based integrated Stepwise Weight Assessment Ratio Analysis (SWARA) and Multi-attributive Border Approximation Area Comparison (MABAC) has been proposed to deal with the issues of material selection for polymer based sustainable composites. Moreover, q-rung orthopair fuzzy numbers (q-ROPFNs) have been implemented to tackle the uncertainty in the information. The effectiveness of the proposed approach has been confirmed by different comparative and sensitivity investigations. The developed composites have shown excellent properties whereas the responses of the materials vary invariably with compositions. The proposed method has identified the amalgamation of 10 wt percentage of rice husk ash and 10 wt percentage of sand with 80 wt percentage of high-density polyethylene (HDPE) as an appropriate material for the development of sustainable floor tiles as the composites resulted to optimum mechanical performances and minimum abrasive wear. The proposed model gives reliable and robust results and is sensitive to the criteria weights and mathematical parameters. The outcome of the research has exposed that the suggested mathematical approach can be effectively applied for material selection of sustainable polymeric composites for different applications.

Concrete properties with recycled coarse aggregate and rice husk ash: factorial design study

Methods of design of experiment have been implemented for the evaluation of the impact of the inclusion of recycled coarse aggregates (RCA) and rice husk ash (RHA) on strength and other chosen parameters of concrete. A specific general factorial design method, two-way analysis of variance (Anova), has been used for the current exploration considering two key factors – that is, percentage of RCA (0% and 100%) and percentage of RHA (0%, 5%, 10%, 15%, 20%, 25%, 30% and 35%). This approach has been used to assess the effect of these materials on various concrete properties, including 3, 7, 28 and 90 days compressive strength, modulus of elasticity, water absorption, volume of voids and density. The outcomes of the analysis have been presented in the form of Anova table, individual, main effect, contour and interaction plots. The results of the analysis show that the levels of RCA and RHA had a significant effect on the properties of concrete.

Synthesis of geopolymer mortar from biomass ashes and forecasting its compressive strength behaviour

The global warming dilemma raised an exigency toward sustainability in the construction industry and compelled scientists to hunt for alternative binders in construction materials. The, geopolymerization as a spectacular technology has arisen as a looming solution to this dilemma. This work assesses the features of geopolymer mortar developed with both industrial and agricultural wastes at ambient temperature curing. The geopolymer mix proportion was evolved in this study using main precursor material as fly ash, ground granulated blast furnace slag (GGBFS), sugarcane bagasse ash (SCBA) or rice husk ash (RHA). Workability and mechanical properties, including compressive strength, flexural strength, and split tensile strength of different mortar mixes with various percentages of RHA and SCBA for 365 days, were evaluated. Geopolymer mortar with 10 % SCBA and 5 % RHA achieved improvements of 25 % and 13.91 % in compressive strength, 10.6 % and 3.5 % in flexural strength, and 35 % and 16.8 % in split tensile strength, respectively. Good geopolymer gel formation is clearly evident from the SEM images of SCBA mortar. The main polymeric bonds Si–O–Al and Si-O-Si are also identified using FTIR. To assess the efficacious use of biomass ashes, resistance to chemical attack using H2SO4, HCl, Na2SiO3, and NaCl solutions for 365 days was studied. It was revealed that SCBA incorporated geopolymer mortar specimens achieved good resistance compared with RHA geopolymer mortar. The relation between the ambient temperature cured geopolymer specimen compressive strength at 28 days and 365 days chemical solution curried geopolymer specimen compressive strength find out using python and obtained R2 values more than 95 %. Also, this research proposed various machine learning techniques such as long short-term memory, support vector regression, random forest regression, XGBOOST, and AdaBOOST algorithms for the prediction of compressive strength of geopolymer using 724 mixture proportions with diverse curing temperatures and varying ages. The XGBOOST algorithm achieved the highest R² value of 0.92, demonstrating its effectiveness for the strength prediction.

The Optimum Percentage of Rice Husk Ash (RHA) as Partial Cement Replacement in Engineered Cementitious Composite (ECC)

Rice Husk Ash (RHA) is a potential supplementary cementitious material (SCM) in concrete production due to their capability of pozzolanic reaction. This research study on the fineness, workability and compressive strength of the RHA incorporated into Engineered Cementitious Composites (ECC) as a cement replacement alternative hence to determine the optimum percentage of RHA to be use in the ECC mix. The mix proportional of RHA-ECC was designed with RHA as the substitution of Portland cement at various percentages by volume, including 5%, 10%, 15% and 20% respectively. Physical characterization of RHA was determined by particle size distribution test. The workability of hand mixed mortar was determined by the flow table test. A total of 45 cubes of 50×50×50 mm was prepared and cured for 7, 14 and 28 days. These hardened mortars were test with the compressive strength test to study its mechanical property. Findings showed that the workability of RHA-ECC was decreased with increasing of the amount of RHA added. The compressive strength of RHA-ECC was best at 28 days with the 10% of replacement level compared to others. This study will provide both direction and knowledge on the application of RHA as a greener and sustainable cement replacement.

Effect of rice husk ash on soil stabilization at Dinajpur City

Understanding local conditions is crucial for applying soil stabilization principles from other regions to a specific country for effective and sustainable stabilization methods. This investigative study delves into the suitability of locally available Rice Husk Ash (RHA) for incorporation into local building construction practices at Dinajpur, Bangladesh, aiming to minimize the volume of waste disposed of in the environment, thereby mitigating environmental pollution. Conventional soil stabilization techniques are becoming increasingly expensive due to the rising costs of stabilizing agents such as cement. Replacing a portion of the stabilizing agent with RHA could potentially reduce the cost of stabilization while also minimizing environmental harm. RHA comprises 85-90% silica, making it an excellent substitute for silica in soil stabilization. Silica is recognized as an effective binding agent alongside cement. The soil sample selected for this research is a highly plastic clay (CH), which necessitates significant strength enhancement. Three soil samples were stabilized with varying percentages of RHA and a minimal amount of cement. Observations were made to assess the changes in soil properties, including Maximum Dry Density (MDD), Optimum Moisture Content (OMC), and Unconfined Compressive Strength (UCS). The results obtained indicate that increasing RHA content leads to an increase in MDD but a decrease in OMC. Additionally, the UCS of the soil exhibits substantial improvement to up to 88% with increasing RHA content up to 10%. Based on the observed maximum strength enhancement, a 10% RHA content combined with 6% cement is recommended as the optimal combination for practical applications.

Assessment of the potential of rice husk ash (RHA) as a supplementary material in binary blended cement for road pavement applications

The current study explores the feasibility of using rice husk ash(RHA) as an additive in PPC (Portland Pozzolana Cement) concrete for rigid road pavement. The research investigates the impact of RHA on concrete’s strength parameters, specifically tensile, split tensile and compressive strengths. The conventional mix design method is applied for the controlled concrete, serving as baseline for designing mixes with varying percentage of RHA as a replacement for cement. The study examines five replacement levels: 5%, 7.5%, 10%, 12.5%, and 15%. Various curing durations are tested, including 3 days, 7 days, 28 days, and 56 days. The primary focus is to determine the optimal quantity of RHA as a cement replacement through experimental analysis. Key findings reveal that for compressive strength, the optimal replacement level is 10% RHA, while for flexural strength, the optimal replacement level is 5% RHA. These results underscore the potential of RHA to enhance concrete performance in road pavement applications when used judiciously as a partial substitute for cement.

Synergistic effects of supplementary cementitious materials and compressive strength prediction of concrete using machine learning algorithms with SHAP and PDP analyses

In order to reduce the CO2 associated with cement production, this study explored the potential of rice husk ash (RHA) and fly ash (FA) as supplementary cementitios materials for partially replacing cement in concrete production. The study aimed to analyze the synergistic effects of a cement-based mixture consisting of RHA and FA in different proportions on concrete's fresh, hardened, non-destructive and microscopic properties. In addition to the experimental work, this study successfully applied machine learning to predict the compressive strength of RHA-FA concrete using three types of algorithms: ANN (Analytical Neural Network), XGB (Extreme Gradient Boosting), and GBM (Gradient Boosting Model). A total of 138 data points were used for this prediction, and statistical and parametric analyses were performed to define the impact of input parameters on the outcome. Furthermore, both destructive and non-destructive tests were conducted on hardened concrete, including compressive strength, split tensile strength, ultrasonic pulse velocity (UPV), and rebound hammer. The scanning electron microscope (SEM) was operated to analyze the microstructural characteristics of concrete. The compressive and split-tensile strength test results showed that the mixture with a higher percentage of fly ash and a lower percentage of rice husk ash achieved maximum strength. The X-ray Fluorescence (XRF) analysis revealed that both ashes contained a significant amount of silica, which gave them excellent pozzolanic properties. After 28 days, both the UPV and the rebound hammer strength align with the destructive compressive strength results. The study also employed SHAP (SHapley Additive exPlanations) and PDP (Partial Dependence Plot) analyses to identify the optimal range for each parameter's contribution to strength improvement. The machine learning models exhibited a strong correlation with the test results, achieving an R2 value of 0.84 for the XGBoost model.

Experimental investigation on properties of concrete with rice husk ash and water hyacinth ash

The purpose of this experimental investigation is to study the properties of concrete with Ricehusk ash (RHA) and Water hyacintha ash (WHA) when used as a partial replacement for cement. Ricehusk ash is a by- product of thermally treating rice husks. It is highly pozzolanic and has been used as a partial replacement for cement in concrete production and Water hyacinth grows vigorously in ponds and doubles the quantity within two weeks. The studies have been done to evaluate water hyacinth ash in the replacement of cement. This study seeks to determine the effect of RHA and WHA on the strength and other properties of concrete. To conduct this investigation, a series of concrete mixtures were prepared with various percentages of RHA (5%, 10%, 15%, and 20%) for finding the optimum percentage. To the optimum concrete made with rice husk ash different percentage of cement is replaced with water hyacinth ash (5%,10%,15%,20%) and the optimum is obtained. The mix proportions were determined according to the standards. The mixtures were then tested to determine the compressive strength and flexural strength of the concrete. The results of the investigation showed that the replacement of cement by RHA enhanced the strength properties of concrete in 15% replacement of cement with RHA shows the maximum compressive strength value. The replacement of cement by WHA 10% with optimum RHA 15% enhanced the strength properties of concrete. Replacement of cement by 10% WHA with optimum RHA shows the maximum compressive and tensile value.

The Effects of the Rice Husk Ash (RHA) and Cement on California Bearing Ratio in Laterite Soil Stabilization

Lateritic soil is a problematic type of soil because it must be stabilized in order to meet geotechnical criteria for engineering purposes. As a result, cement has been frequently utilized to increase soil strength in order to make it more stable. As a result, several ways for minimizing the amount of cement used, such as the utilization of waste materials or industrial by-products, such as Rice Husk Ash (RHA), have been developed. The purpose of this study was to investigate the properties of laterite, rice husk ash, and cement, as well as the effect of different percentages of RHA and cement on the California Bearing Ratio (CBR) of laterite soil. In current soil stabilization, different amounts of RHA and cement are used, specifically 5%, 10%, and 15%, to determine an appropriate combination that will function. Soil samples were tested using the CBR and preliminary tests such as the Liquid limit and Plastic limit to identify index characteristics and the proctor test to determine Maximum Dry Density and Optimum Moisture Content. Data analysis was carried out to assess how well the RHA/cement mixture performed in CBR. The soil sample with 2.5% RHA and 2.5% cement produced the highest result in California Bearing Ratio, 34.45 % at 2.5mm penetration and 28.48 % at 5.0mm penetration. Hence, the objective of this study was met when using RHA as a partial replacement for cement in laterite soil stabilization enhanced the value of the California Bearing Ratio.

Mechanical and microstructural study of slag based alkali activated concrete incorporating RHA

The objective of the present research is to evaluate the effect of incorporation of rice husk ash (RHA) into ground granulated blast furnace slag (GGBS) based alkali activated concrete (AAC) at ambient temperature to develop a cement free binder that composed of waste products. The hardened properties of AAC have been evaluated in accordance with Indian Standard code in terms of destructive tests such as compressive, splitting tensile and flexural strength, as well as non-destructive tests such as rebound number, ultrasonic pulse velocity (UPV) and dynamic modulus. Using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR), the microstructural characteristics of AAC mixes were evaluated. The outcomes of the test indicate that the compressive strength of AAC achieves maximum strength when RHA component of up to 10% is incorporated into the AAC mixture. The compressive strength declined beyond 10% RHA, however the AAC has lower strength of 39.5 N/mm2 (M7 mix at 7 days) among all mixes, which was adequate for the structural applications. Corresponding to compressive strength, the split tensile and flexural strengths exhibit similar performance. Statistical analysis also carried out to determine the correlation between different parameters. The SEM test shows the formation of dense microstructure at a lower percentage of RHA content in the mix, whereas cracks and voids were detected in case of a higher percentage of RHA. Therefore, using GGBS with lower RHA content as binder cured at ambient temperature enhances the performance of AAC and also facilitates the use of AAC instead of ordinary concrete.

Application of rice husk ash in brick aggregate concrete to improve the permeability and resistance against acid and sulfate attack

AbstractBrick‐aggregate‐concrete with a greater permeability is susceptible to decay at a faster rate under the action of acid and sulfate. This study tries to improve the durability of brick aggregate concrete by the addition of rice husk ash, which has been termed brick‐ash concrete in this paper. The permeability and sorptivity of stone‐aggregate‐concrete, brick‐aggregate concrete, and brick‐ash concrete samples with different percentages of rice husk ash and different water‐to‐binder ratios were investigated. The concrete samples were also exposed to 1.5 % hydrochloric acid and 5 % sodium sulfate along with periodic drying and wetting cycle and periodic observations in terms of compressive strength, weight loss, and ultrasonic pulse velocity test for 360 days. 5 % to 10 % rice husk ash can significantly improve the permeability and resistance to the harsh environment of brick aggregate concrete. Additionally, this study also presents the equations to predict the actual strength from ultrasonic pulse velocity values for the brick ash concrete specimen exposed to acid and sulfate environments.

Evaluation of the readiness of clay bricks with partially replaced rice husk ash

Environmentally acceptable alternatives are replaced for the raw construction materials to alleviate sustainability concerns with construction materials. Rice husk ash, an agricultural byproduct, can be substituted in the production of construction materials. In this study, the effect of adding rice husk ash from organic agricultural waste on brick quality is explored. In this study, four sets of bricks are cast with various percentages of rice husk ash, ranging from 0% to 20% with a 5% increment, and then burned in a furnace for varying durations of time. This research examines the compressive strength and water absorption of bricks containing varying concentrations of rice husk ash. According to the findings, an increase in rice husk ash reduces compressive strength and increases water absorption. The present findings reveal that a brick containing 5% rice husk ash has a higher compressibility of 4.70 N/mm2 and a decreasing compressive strength as the proportion of rice husk ash increases. The results also demonstrated an 11.65 % reduction in water absorption at a rice husk ash concentration of 5 %, and the absorption rate increases consistently up to 10 % rice husk ash before decreasing with a further increase in rice husk ash. Therefore, the technology of creating bricks by casting combinations of clay, sand, and rice husk ash is not only useful for constructing walls but also for reducing environmental pressure and promoting sustainable development.

Stabilization of soil using kenaf fibre and rice husk ash

One of the most essential engineering challenges is stabilizing soils because it affects the long-term strength and functionality of structures. In some places, the soil might be too weak to resist the oncoming masses. Natural materials and waste materials are often used to investigate soil stabilization characteristics. The objective of this study is to investigate the impact of adding rice husk ash (RHA) and kenaf fiber on the properties of soil, such as density, optimum moisture Content (OMC), shear strength, unconfined compression strength (UCS), and California bearing ratio (CBR). Material is chosen for stabilizing clay soil as rice husk ash (0 to 12.5%) with an increment of 2.5% and kenaf fiber (0 to 1%) with an increment of 0.25%. Standard proctor compaction test, Unconfined compression strength, Direct shear strength, CBR, and Permeability characteristics were measured. The optimum percentage of Rice husk ash was identified as 10%. The coefficient of permeability increases with the use of kenaf fibre addition in the soil. Unconfined compressive strength, shear strength, and CBR shows an increasing trend using kenaf fibre in soil mixes. By analysing the above parameter, 0.75% of kenaf fiber is considered identical for stabilizing soil.

Use of rice husk as a source of silica for the production of self-flowing refractory castables

The objective of this study was: i) to obtain rice husk ash (RHA) with high purity silica for the production self-flowing refractory castables with different percentages of RHA as a partial substitute for microsilica; ii) analyze the mechanical, physical, thermal, and microstructural properties of the formulations studied in relation to the effect of firing temperatures. The rice husks were washed with acetic acid in autoclave, dried at 105 °C for 24 h and calcined at 600 °C for 4 h. The ashes obtained were analyzed by particle size distribution, X-ray fluorescence spectrometry (FRX), X-ray diffraction (XRD) and scanning electron microscopy with X-ray microanalysis (SEM-EDS). The presence of amorphous silica of high purity was verified with irregular grains and sizes between 40 and 145 μm. Refractory castables were produced by replacing 0%, 5%, 10% and 15% (mass) of the microsilica by rice husk ash. After curing, the specimens were dried at 110 °C for 24 h and a part was sintered at 800 °C for 5 h, while the other was sintered at 1430 °C for 8 h. The samples were submitted to tests of free creep; apparent density; linear variation; resistance to bending, compression and thermal shock. The formulation with the best mechanical performance, modulus of rupture (55.10 MPa) and compressive strength (119.62 MPa), was 10% replaced by rice husk ash and sintered at 1430 °C. This result was due to the formation of higher strength alumino-silicate phases and stronger bonds between the matrix and the aggregates. In addition, all analyzed materials using rice husk ash showed high density and good resistance to thermal shock, which is desirable for self-flowing refractory castables.

Rice husk ash-carbide lime as an alternative binder for waste foundry sand stabilization.

Rice husk ash (RHA) is an excellent pozzolana and associated with hydrated lime (HL), it becomes an alternative binder to Portland cement in soil stabilization. In the context of waste valorization, waste foundry sand (WFS) and carbide lime (CL) have been investigated in civil construction and environmental geotechnical applications. However, stabilizing WFS with alternative binders to Portland cement represents a large field of research to be explored. This study evaluated the stabilization of WFS with a binder based on RHA and CL, compared to the use of RHA-HL. An experimental design was carried out to evaluate the influence of different dry-specific weights (12.00, 12.75, and 13.50 kN/m3), RHA contents (10%, 20%, and 30%), and curing times (28, 60, and 90days) under unconfined compressive strength (UCS). UCS results were submitted to statistical analysis and correlated to the porosity/binder content index (η/Biv). Healing capacity, mineralogy, microstructure, and leaching of metals from mixtures of interest were evaluated. The results showed that higher specific weights and higher percentages of RHA promoted better strength. The η/Biv0.28 index proved to be an adequate parameter to assess the UCS of WFS-RHA mixtures with different limes (CL and HL), lower porosity, and higher binder content leading to higher strengths. The mixture's mineralogy and microscopy showed the formation of cementing gels, corroborating the strength gains. WFS stabilized with both binders (RHA-CL and RHA-HL) presented satisfactory environmental performance, allowing the immobilization of metals in the waste compositions.

Development of brick by utilizing rice husk ash as the partial replacement for clay

The study was conducted at Sylhet Agricultural University Campus to find out how adding rice husk ash (RHA) affected the characteristics of Sylhet clay bricks. The goal of the study was to establish the ideal RHA percentage to utilize in brick production as well as the impact of RHA on the water absorption, compressive strength, shrinkage, density, and thermal properties of bricks. Therefore, an attempt has been made by using RHA from 5-20% by weight as clay replacement for bricks. The study figured out that water absorption of bricks increases with the increasing percentage of RHA. Brick containing 5% RHA showed the lowest water absorption, which was 17.8%, and the highest was 21.33% for 20% RHA-containing brick. It was also found that the highest compressive strength among all types of bricks was 8.401 N/mm2 for 5% RHA-containing brick. Similarly, the brick containing 5% RHA had the maximum density (1676.395 Kg/m3) and thermal conductivity (0.584 Wm-1K-1) of all the bricks combined with rice husk ash. The study also revealed no significant changes in shrinkage for all RHA Bricks and the percentages were the same, which was 14.28%. From the investigation, it is seen 5% rice husk ash can be the optimum percentage when mixing with clay and can be used in replace of first-class as well as second and third-class Manual Handling bricks, which are used in the construction of internal walls, foundations, and in temporary structures, respectively.

An experimental study on rice husk ash concrete

Rice husk consists of a huge amount of silica when it is burned properly, and cement can be partially replaced by rice husk ash (RHA) to make concrete. In the present experimental research, flexural strength (FS), workability, compressive strength (CS), and indirect split tensile strength (STS) of M30 grade concrete are investigated by partially replacing cement with RHA with an increment of 5%. The influence of the various percentages of RHA as a cement substitution material on the workability, CS, STS, and FS is compared with that of normal M30 grade concrete. The water-cement ratio is 0.55, which is maintained constant. The test results also concluded that the CS, STS, and FS of concrete decreased with an increase in RHA above 15%. The findings of the experimental research show that the optimum percentage of RHA was 15%, at which point the CS, STS, and FS were at their maximum, and any additional RHA addition beyond 15% causes a significant decrease in the CS, STS, and FS, and that it is recommended to replace cement with RHA in the range of 5–15% to achieve an effective and high strength of concrete.11Corresponding Author: E-mail address: sandeepsatheresearch@gmail.com (Sandeep Sathe)

The test performed on the sample is tensile test and surface morphological test. It is observed that the tensile strength of the composite increased when the percentage of rice husk ash added increased. The highest tensile strength of the composite is at 10% rice husk ash reinforced with 10% bamboo charcoal powder and 90% polypropylene with value of 23.15 MPa. Overall, the proportion of 10% rice husk ash reinforced with 10% bamboo charcoal powder and 90% polypropylene showed the best result to enhance the wood plastic composite.

Wear and microstructure analysis of aluminium based composite using eggshell and rice husk ash as reinforcement

PurposeThe purpose of this paper is to study Al-based green composite. To make composite samples of aluminium alloy (AA3105) with different weight percentages of rice husk ash (RHA) and eggshell (ES) particles as reinforcement, stir casting method was used.Design/methodology/approachSeveral other aspects, including the weight percent of reinforcing agent particles, the applied stress and the sliding speed, were taken into consideration. During the course of the wear test, the sliding distance that was recorded varied from a minimum of 1,000 m all the way up to a maximum of 3,135 m (10, 15, 20, 25 and 30 min). The typical range for normal loads is 8–24 N, and their speed is 1.58 m/s.FindingsWith the AA/ES/RHA composite, the wear rates decreases when the grain size of the reinforcing particles enhanced. Scanning electron microscopy images of worn surfaces show that at low speeds, delaminating and ploughing are the main causes of wear. At high speeds, ploughing is major cause of wear. Composites with better wear-resistant properties can be used in wide range of tribological applications, especially in the automotive industry. It was found that hardness increases at the same time as the weight of the reinforcement increases. Tensile and hardness were maximized at 10% reinforcement mix in Al3105.Originality/valueIn this work, ES and RHA has been used to develop green metal matrix composite to support green revolution as promoted/suggested by United Nations thus reducing the environmental pollution.
