Stabilization of subgrade with expansive soil using agricultural and industrial By-products: A review

Expansive soils cover a large part of India and possess certain undesirable engineering properties such as low bearing capacity and large volumetric changes which causes severe damage to the pavements. Therefore, it is necessary to improve the geotechnical properties of expansive soils so that it becomes easier to construct pavement using these expansive soils. Agricultural and industrial byproduct such as rice husk ash, sugarcane bagasse ash, fly ash, plastic waste, coir pith and fiber, calcium carbide residue, cement kiln dust, silica fume and red mud etc. are found to be useful in pavement construction. Studies have reported that the strength of stabilized soils significantly improved with the use of various types of industrial and agricultural byproduct. If these waste materials are available locally for soil stabilization, it leads to the development of cost-effective and sustainable pavement construction. Further, utilization of these byproduct as a soil stabilizer also solve the problem of their disposal. As a result, the environmental problems caused by these byproducts from industrial and agricultural will be reduced. The research paper provides an overview of the utilization of different byproducts from industry and agriculture that have been used in soil stabilization as strengthening agents.

Utilization of industrial and agricultural waste materials for the development of geopolymer concrete- A review

Concrete is a highly consumed construction material. Cement is the first and foremost ingredient in the manufacture of concrete. Manufacturing of cement results in emission of an equal amount of carbon dioxide. These greenhouse gases cause global warming. The utilization of environment-friendly construction materials has been identified to be most essential to overcome environmental issues. An ecofriendly concrete such as geopolymer concrete founds to be an alternative for cement concrete. Geopolymer concrete (GPC) is a sustainable construction material as it can reduce carbon dioxide emission by utilizing industrial and agricultural waste by-products. Hence in this context, to reduce global warming, usage of cement can be minimized by replacing it with other materials such as Fly ash, Silica fume, Red mud, Ground granulated blast furnace slag, Metakaolin, Rice husk ash, Corncob ash, Sugarcane bagasse ash etc. These materials have been utilized to prepare geopolymer concrete with good mechanical strength, durability and thermal resistivity. A lot of research has gone into the development of sustainable geopolymer concrete utilizing various industrial and agricultural waste. This review paper is on the research on the utilization of industrial and agricultural waste materials to produce sustainable geopolymer concrete.

An experimental study on tensile as well as flexural strength of concrete by using sugarcane baggase ash & steel fiber

Generally the concrete is weak in tensile as well as flexural strength which are some basic strength properties of any structure. Steel fiber can be potentially used in the concrete to improve its structural strength. Use of steel fiber in the concrete will also reduce the steel reinforcement requirements at later stage. Concrete was prepared in the present research work in which sugarcane bagasse ash was used to substitute cement to minimize cement use and thereby reduce construction costs. In this work concrete beams & cylinders were cast in various proportions of SCBA like 5%, 10%, 15%, and 20%. This combination was further enhanced by adding steel fiber by volume in percentages like 0.5%, 1%, and 1.5%. The beams & cylinders were prepared using this combination and tested at different curing ages, such as 7-days, 28-days, 56-days and 90-days. At such ages, concrete properties such as flexural strength and split tensile strength were analyzed. In this study it is clearly evident that use of steel fibers are improve the tensile strength of concrete but in combination of SCBA with 10 % replacement of cement gives the best result in case of flexural strength.

Carbonation and chloride penetration of repair mortars with water treatment plant sludge and sugarcane bagasse ash sand

Water treatment plant sludge (WTPS) and sugarcane bagasse ash sand (SBAS) (wastes from water treatment and sugar/ethanol industries) can be used as replacements of natural sand in concrete. Thus, this paper aims to evaluate carbonation depth and chloride penetration of cementitious repair mortars produced with WTPS and SBAS. Three mortars compositions were analysed: plain reference sample (REF); sample with 3% of WTPS (3WTPS); and sample with 30% of SBAS (30SBAS). They were subjected to tests of accelerated carbonation and immersion in NaCl solution up to 84 days (12 weeks). The results showed that SBAS mortars had the best performance in relation to carbonation and chloride penetration tests. 3WTPS mortars had similar results to the reference sample. This is due to refinement of pores given by incorporation of fine waste materials making it difficult for aggressive agents to penetrate cement matrices. Therefore, 3WTPS and 30SBAS composites can be satisfactorily used in buildings repair services for more sustainable and durable construction.

Strength Performance of Mortar Containing Bagasse Ash and Rice Husk Ash as Cementitious Material

The use of cement as a main binding materialin the field of civil engineering is no doubt at the next level due to growth inurbanization.It is mainly used to make cementmortar, concrete, and other composite construction material. The extensive use of OPC in the constructionindustry has caused increment in the production of CO2at atmosphere. This has deteriorated theenvironment and has urged everyone to study and research the sustainable progress by using differentwaste products as replacement in concrete and mortar. Therefore, the purpose of this study was toinvestigate the strength performance of cement mortar containing Sugarcane Bagasse Ash (SCBA) andRice Husk Ash (RHA) as a Cementitious Material. In this study, we have substituted the cement withdifferent percentages i.e.,0%, 5%, 10% and 15% of both sugarcane bagasse ash (SCBA) and rice husk ash(RHA) to obtain sustainable mortar. Flowability, Density and compressive strength wereexamined by casting 36 standard cubes of 50mm size and cured for 3, 7 and 28 days. Testoutcomes indicated that the flowability of mortar paste kept on decreasing with the increase in partialreplacement bySCBA and RHA. As we have fixed the water cement ratio for all type of mixi.e., 0.5.From the outcomes of Density and Compressive Strength of Cubes cured in plain water, we come to knowthat as % replacement was increasing the density and compressive strength of cubes cured was reducing.For Compressive Strength, it wasfound that at each specified day, the compressive strength of cubes up to10% replacement has given a reasonable value but intensely decreased at 15% replacement. At 5%replacement of both SCBA and RHA on 28th day test it was pointed that compressive strength of cubeshas the highest values for all % of replacement.

Properties of binary and ternary mixes of cement, sugarcane bagasse ash and limestone

Cements with low clinker content are an important alternative for sustainable development of the cement industry. In this respect, the present study aimed the production and characterization of binary and ternary mixes of cement, sugarcane bagasse ash (SCBA) and limestone in order to assess the physical and chemical effects of these materials in cementitious systems. Pastes and mortars were produced using the different cements to assess their performance in rheology, isothermal calorimetry, chemical shrinkage, and compressive strength tests. All cements with SCBA were characterized as pozzolanic Portland cements, justifying the increase in chemical shrinkage in relation to the reference. Adding both materials changed the rheology of mixes, increasing rheological parameters, primarily in pastes with SCBA. Limestone accelerated hydration during the first few days due to the heterogeneous nucleation effect, but compressive strength declined at 7, 28, and 90 days owing to the dilution effect. SCBA initially delayed paste hydration, but increased compressive strength compared to the reference at all studied ages due to pozzolanic reactions. The performance of ternary mixes was intermediate in relation to binary SCBA-cement and limestone-cement, suggesting the joint effect of the additions on the properties assessed.

Bentonite blended with bagasse ash as an adsorbent for reactive red 198 dyes

Abstract Adsorption offers an efficient, cost-effective, and eco-friendly method for the treatment of dye-laden wastewater. This work presents reactive red 198 (RR198) removal by adsorption using bentonite clay (BC) blended with sugar cane bagasse ash (SCBA). The adsorbent's surface morphologies, crystalline phase structures, functional groups, and specific surface before and after adsorption were examined using SEM, XRD, FTIR, and BET respectively. Central composite design (CCD) under response surface methodology (RSM) was applied to optimize independent and dependent variable values. The optimal parameters for RR198 removal using the blended adsorbent were 107 minutes contact time, 0.934 g/L adsorbent dose, and 15 mg/L initial dye concentration, and 85.2% RR198 removal efficiency was achieved. The sorption isotherms and kinetics were evaluated using various existing models. The Freundlich isotherm model (R2 = 0.95) and the pseudo-second-order equation best described the adsorption parameters and the RR198 adsorption kinetic mechanism, respectively. Desorption and reusability experiments in batch study confirmed that BC blended with SCBA can be used multiple times for dye removal from wastewater.

Preparation of Iron-Doped SiO<sub>2</sub>/TiO<sub>2</sub> Using Silica from Sugarcane Bagasse Ash for Visible Light Degradation of Congo Red

Iron(III)-doped SiO2/TiO2 composite (SiO2/TiO2-Fe) has been prepared from sugarcane bagasse ash for photocatalytic degradation of Congo Red. This research was initiated by preparing SiO2 from sugarcane bagasse ash through a sol-gel method. The SiO2/TiO2-Fe was obtained by mixing SiO2 gel with TiO2-Fe sol which was produced with titanium tetraisopropoxide (TTIP) as precursor and FeCl3·H2O as the dopant source. Dopant concentration was varied by 0, 1, 3, 5, 7% (w/w). The prepared materials were characterized by FT-IR, XRD, SR-UV, XRF, SAA, and SEM-EDX. The photocatalytic activity was evaluated for Congo Red degradation in a closed reactor under visible light illumination. The degradation yield was determined by the UV-Visible spectrophotometry method. Results showed that SiO2 was successfully extracted from bagasse ash with a silica content of 90.87%. The SiO2/TiO2-Fe composite was successfully prepared with the bandgap energy value (Eg) decreasing as the dopant concentration increased. The optimum Eg of 2.63 eV was obtained at the concentration of Fe was 5%. Under that condition, the SiO2/TiO2-Fe photocatalyst degraded Congo Red solution by 98.18 % under visible light at pH 3 with a mass of 30 mg for 90 min. The SiO2/TiO2-Fe composite is expected to be a photocatalyst material candidate for dye wastewater treatment.

Effects of the use of agricultural ashes, metakaolin and hydrated-lime on the behavior of self-compacting concretes

Self-compacting concrete (SCC) is an innovative product, which has fluidity and cohesion to cover the entire length of the piece and fill the spaces between reinforcement. However, currently, its use in construction sites is linked to a high consumption of cement. This generates a series of environmental problems such as depletion of natural resources and increased CO2 emissions. To mitigate these environmental problems, it is necessary to seek supplementary, locally available materials, to provide a sustainable and efficient way forward for the construction industry. In this perspective, this research investigates the effects of the use of metakaolin (MK), sugar cane bagasse ash (SCBA), rice husk ash (RHA) and hydrated-lime (HL) on rheological (slump flow, J-ring and V-funnel), mechanical (compressive strength) and durability (electrical resistivity, accelerated carbonation and mercury intrusion porosimetry) behavior in SCC. Portland Cement was replaced from 0% to 60% by mineral admixtures in mixtures with and without 10% HL. The results indicated that the SCC produced with agricultural ashes presented physical behaviors compatible with the standards and obtained compressive strength equivalent to the reference SCC (REF). Moreover, these concretes presented carbonation depth lower than the normative values and electrical resistivity significantly higher than the SCC-REF, reducing the probability of corrosion of the steel bars and, therefore, validating the use of ash obtained from industrial bio-waste in the production of SCC. The HL also presented itself as a good re-alkalizer of the cement matrix.

Stabilization of Johor Peat Soil using Sugarcane Bagasse Ash (SCBA)

Peat soil have been categorized as a problematic organic soil, because they have a high settlement rate when placed any structure on it. Therefore, the peat soil must first be stabilized using cement before it can be used. However, massive use of cement can lead to environmental pollution. Therefore, this study intends to use sugar cane bagasse ash as a substitute for cement in peat soil stabilization. The mix ratio of 5% to 20% was used to find the optimal mix ratio. Various tests were carried out on samples such as basic properties tests, Unconfined Compressive Strength (UCS) and Scanning Electron Microscope (SEM). After all the tests, the 5% replacement SCBA mix ratio gave the highest unconfined compressive strength if compared to the other mixtures ratio. Therefore, it is selected as the optimum mix ratio. The soil strength achieved by the SCBA 5% replacement ratio was found to be higher than cement stabilization alone due to the presence of secondary pozzolan reactions. The microstructure result from the SEM test had shown that the 5% replacement SCBA mix ratio filled in the hollow left by the peat soil. Hence, able to improve its soil structure and thus increasing its strength.

Feasibility of ECC with high contents of post-processed bagasse ash as partial cement replacement

This study investigated the feasibility of using high contents of post-processed sugarcane bagasse ash (PBA) as a partial replacement of cement for the development of Engineered cementitious composites (ECCs) with low amounts (1.5% by volume) of non-oil-coated polyvinyl alcohol (PVA) fibers. PBA was prepared by sieving, burning, and grinding raw sugarcane bagasse ash collected from a sugar mill. Composites using three different replacement levels of cement with PBA (i.e., 40%, 50%, and 60% by mass) were evaluated and compared to a composite without PBA (i.e., PBA-0) and a composite using Class F fly ash (FA) at 60% cement replacement (i.e., FA-60). This study evaluated fiber-bridging properties via single crack tensile tests (SCTT), matrix properties via fracture toughness tests, mechanical properties via compressive strength and uniaxial tensile tests, and physical properties via surface resistivity and flow tests. Results showed that the workability of the mixtures decreased with the increase in PBA content. Furthermore, the incorporation of PBA resulted in a reduction in compressive strength (up to 39.1%) and improvements in surface resistivity. Importantly, PBA composites outperformed the FA composite in compressive strength and surface resistivity. The use of PBA produced reduction in the crack-tip fracture toughness (Jtip). SCTT revealed that the complementary energy of the fiber-bridging relation (Jb') was positively affected by PBA up to 50% cement replacement; yet, at 60% cement replacement, Jb' substantially decreased compared to PBA-0. Jb' increments were attributed to a likely decrease in the fiber/matrix interface chemical bond, whereas the decrease at the 60% cement replacement was attributed to fiber clumping due to the poor workability of the mixture. The fiber-bridging capacity and tensile strength of the composites exhibited a similar trend, where the mixture using 40% cement replacement with PBA showed the highest values and the one using 60% showed the lowest value. All PBA-composites exhibited higher tensile strain capacity compared to PBA-0, and the highest improvement (i.e., 82.1%) was observed at 50% cement replacement with PBA. However, the tensile ductility of the PBA composites was significantly lower than that of FA-60. It is concluded that PBA can generate comparable fiber-bridging properties as those produced by FA; however, FA is more effective at reducing Jtip, thus producing better conditions for pseudo-strain hardening behavior. Furthermore, the use of high contents of PBA significantly reduces the workability of the composites inhibiting proper fiber dispersion. Therefore, large amounts of PBA as partial cement replacement cannot be used to produce ECCs in conjunction with low amounts of non-oil-coated PVA fibers.

Stabilization of gold mining tailings with alkali-activated carbide lime and sugarcane bagasse ash

Recent tailings dam failures have attracted special attention to the mining sector. These incidents pressured the mining industry to develop more secure and sustainable practices. Geotechnical techniques, such as soil stabilization with ordinary Portland cement (OPC), have been explored as alternatives to this problem. However, OPC production is associated with high energy consumption, exploration of natural resources, and greenhouse gases emission. Thus, alternative materials to OPC, with lower environmental impacts and similar mechanical performance, are growing in interest for stabilization techniques. The present study describes the mechanical behavior of gold tailings stabilized with alkali-activated carbide lime and sugarcane bagasse ash. As a control group, the gold tailings were also stabilized with high initial strength Portland cement (type III). The specimens were tested regarding their unconfined compressive strength, stiffness, and durability. All results were correlated with the porosity/binder index to create a rational dosage methodology for the tailings-cement mixtures. Results have shown that Portland cement mixtures resulted in more expressive strength, stiffness, and durability results when compared to the alkali-activated cement. Nevertheless, the alternative cement was also able to improve the mechanical behavior of the gold tailings. Reduction in porosity and increase in cement content led to the improvement of the mechanical behavior of all specimens. A direct correlation was established between strength, stiffness, and durability. The porosity/binder index was shown to be a viable dosage method to predict the mechanical behavior of stabilized gold tailings, allowing the unification of the results in a single relation, replacing trial and error conventional strategies.

Removal of Lead by Merlinoite Prepared from Sugarcane Bagasse Ash and Kaolin: Synthesis, Isotherm, Kinetic, and Thermodynamic Studies.

This study introduces a merlinoite synthesized from sugarcane bagasse ash (SBA) and kaolin and evaluates its application as an adsorbent to remove lead from wastewater. The synthesis was performed via the hydrothermal method, and optimal conditions were determined. The adsorption of Pb by merlinoite was also optimized. Determination of the Pb2+ remaining in the aqueous solution was determined by atomic absorption spectroscopy (AAS). Adsorption isotherms were mainly studied using the Langmuir and Freundlich models. The Langmuir model showed the highest consistency for Pb adsorption on merlinoite, yielding a high correlation coefficient (R2) of 0.9997 and a maximum adsorption capacity (qmax) of 322.58 mg/g. The kinetics of the adsorption process were best described by a pseudo-second-order model. Thermodynamic studies carried out at different temperatures established that the adsorption reaction was spontaneous and endothermic. The results of this study show that merlinoite synthesized from kaolinite and SBA is an excellent candidate for utilization as a high-performance adsorbent for lead removal from wastewater.
