This research study is for the evaluation of the effect of the burning temperature on the chemical and microstructural properties of Sugarcane Bagasse Ash. The Sugarcane Bagasse Ash (SCBA) is a byproduct of sugarcane which is dumped without proper handling and causing  environmental  issues  because  of  the burning on dump site and loss of the area due to dumping in the commodity. The current research study is conducted for burning of SCBA on different temperatures  and  duration  for  finding the optimum burning temperature and duration of burning. The chemical and microstructural properties of SCBA evaluated at burning temperatures of 800°C for the duration of 01 hour, at temperature of 600° for the duration of 03 and 06 hours by conducting the tests of FTIR, XRD and XRF on the samples. The test results show that the burning temperatures of 800°C for the duration of 1 hour contains amorphous silica and also fulfilling the requirement of pozzolanic material (Composition of Silica, alumina and iron oxide is greater than 70%) as compared to other ash samples of sugarcane bagasse.

This research work has been investigated the agriculture solid waste of sugarcane bagasse ash (SCBA) materials replacing Portland cement and produces the assured quality of concrete. The current research work for various mixes of experimental test results shows the higher compressive strength was 37.51MPa at 28-days, 38.10 MPa at 56-days, the best mix consisting of SCBA (wet sieving method) content up to 15% (by weight of binding materials) along with 1.5% of waste tin fibers and also an excellent improvement trend was noted in flexural rigidity of concrete to addition of tin fibers shows the higher bending stress for all mixes except reference as well as more than 15% of SCBA concrete at different curing days. However, this study focused on the indirect measurement of tensile strength in SCBA concrete obtained the higher split tensile strength was 3.75MPa at 28-days, 3.95MPa at 56-days. It is concluded based on the various test results for different curing days the optimum replacement level of SCBA up to 15% of Portland cement was fixed and achieve the target strength of M25 grade of Portland cement concrete at 28 days.

Industrial waste productions are increased these days, which is causing grief to the environment. Hence it is necessary to cut down the waste generation or reuse the waste. It is needed to utilize the waste to reduce environment damage. It is known that ashes produced from the industries can be used in construction. Ashes like fly ash can successfully replaces the cement showing good results. Researchers are finding the new ways to use ashes in production of cement. Now a days cement manufactures adulterates the cement with pozzolanic material like fly ash, rice husk ash, sugarcane bagasse ash etc. Using these product in concrete, they not only reduces the pollution but also lower the price effectively. If these fillers added in proportion it enhances the properties of concrete like workability, strength, water absorption, permeability etc. considerably. This review paper represents the properties of concrete when cement gets partially replaced by sugarcane bagasse ash, fly ash and rice husk ash. This paper primarily concentrates on the properties like durability and strength when cement concrete contain fillers in it. It also considers the non-destructive tests which are performed.

The increasing demand and scarcity of construction materials like cement and aggregates make the researches all over the world nowadays to focus on finding ways of utilizing industrial wastes and demolished wastes as source of raw materials and eco-friendly alternatives for concrete ingredients. Using recycled aggregates in concrete leads to preservation of the environment and promotes sustainable development. Recycled aggregate is obtained after crushing and screening of the construction rubble from tested laboratory specimens like cubes and cylinders. Sugarcane bagasse ash, the by-product of Sugarcane is the most fibrous material and contains alumina and silica. Bagasse ash used not only to reduce consumption of cement, cost of making concrete and pollution of the environment but also consumes the excess calcium present in the cement improving the durability related properties of concrete. In this work, mix design for conventional M20 grade concrete is made. Based on the literature survey, conventional coarse aggregate is partially replaced by 30% with recycled coarse aggregate. In this 30% recycled aggregate contained concrete, cement is partially replaced by 0, 5, 10, 15 and 20% with Sugarcane bagasse ash. Experimental study was carried out to investigate the mechanical properties. Based on the test results, the optimum replacement level of cement with Sugarcane bagasse ash is observed as 15% for overall efficiency.

Sugarcane bagasse is a fibrous waste product and important biomass sources, which is used as a fuel in the sugar industry. Bagasse ash is an industrial waste that mainly consists of high amount of silica and carbon materials. In this study sugarcane bagasse ash (SCBA) and sugarcane waste ash (SCWA) were calcined at 400°C, 600°C, 800°C and 1000°C for 2 h. These samples were characterized in order to evaluate the possibility of their use in different industries.  XRF and XRD analyses were done for chemical and phase analysis of both calcined samples. The chemical composition of calcined SCBA and SCWA indicated that samples had similar compositions of other pozzolanic material. Carbon content has been determined by elemental analyzer. With increasing temperature the percentage of carbon content decreases in both cases. As temperature increases, the color of SCBA and SCWA samples changing from black to grey and white, which also indicates that the carbon content present in the SCBA were reasonably reduced. XRD patterns showed that crystallinity increases with influence of calcining temperature for both ash samples.

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.

This study is aimed to evaluate the effect of sugarcane bagasse ash fineness on the properties of cement-based composites. Three sugarcane bagasse ash contents (10, 20 and 30% by weight of cement) and three particle sizes of bagasse ash (particles less than 45, 75 and 150 μm) were used as a partial replacement for cement in mortar specimens with a constant water/cementitious ratio of 0.55. The pozzolanic strength activity test, compressive strength test and scanning electron microscope observations were conducted and compared. Test results indicated that the compressive strength decreased with the addition of sugarcane bagasse ash content increased. Addition of sugarcane bagasse ash to replace cement in cementitious composites could provide hydration and pozzolanic reaction, but it would still keep more rugged and some larger pores observed from the paste surface and resulted in the weaker microstructures and poorer properties in cementitious composites. In conclusion, the critical usage of sugarcane bagasse ash is 10 % with 45μm particles.

Since the construction industry is responsible for 30% of the CO2 emissions, one way to reduce the impact of the construction activity is to substitute ordinary Portland cement by pozzolanic materials. The application of using agricultural waste in the production of pozzolanic material is technically feasible, due to the calcination of organic materials and leaving ashes with a fine particle size and high SiO2 content. In the present, it is discussed the pozzolanic effect of sugarcane bagasse ash (SCBA) from Taretan, Michoacán, Mexico, on the physical and mechanical properties of a portland cement mortar. Test specimens were prepared based on replacing sugarcane bagasse ash percentages of 5, 10, 15, 20 and 30 %, relative to the weight of cement. To validate the mechanical properties of the specimens, tensile, flexural and compressive strength was determine. The porosity of the mortar was determined by means of non-destructive ultrasonic testing of pulse rate and electrical resistivity. The contribution of this paper was determine the bond strength of an overlay mortar with SCBA bonded to the concrete substrate by pull-out tests. The results showed that the addition of the sugarcane bagasse ash improved the mechanical strength, adherence of the mortar to concrete, and decreases the porosity on large curing times. Hence, it is suggested the use of Portland pozzolan cement containing sugarcane bagasse ash pozzolan, with the added benefit on the use of agricultural waste.

Portland cement (OPC) production is one of the most contaminating greenhouse gas producing activities. In order to reduce OPC consumption, several alternatives are being assessed, and the use of pozzolanic material is one of them. This paper presents study on the reactivity of sugarcane bagasse ash (SCBA), a residue from sugarcane industry, as a pozzolanic material. In order to evaluate SCBA reactivity, it was mixed in pastes with hydrated lime and OPC, which were microstructurally characterised. These studies showed that SCBA presents some pozzolanic characteristics. Studies on mortars in which OPC was replaced by SCBA in the range 10–30% were also carried out. Replacement in the range 15–20% yielded the best behaviour in terms of compressive strength. Finally, it can be concluded this ash could be valorised despite its relative low pozzolanic reactivity.
