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.

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 consumption of construction materials create a bottle neck shortage of construction materials this make the researcher and engineer to focus on new material and method for waste reduction and this is for the cost-effective, green and scientific reasons. Sugarcane bagasse ash (SCBA) which is obtained as a secondary product from sugar industry has relatively high silica content has the capacity to react with cement, contribute in increasing the strength of concrete. Copper slag (CS) the secondary manufactured goods from the process of being making copper, it is absolutely lifeless substance that their characteristics are exactly matching with usual sand which is used in construction and may be replaced in concrete. The effect of earthed Sugarcane bagasse ash (SCBA) and copper slag (CS) on the strength and flexural behavior is studied. A total of 25 % SCBA by mass was replaced in case of Portland cement and a total of 60 % by mass of CS was used as a fine aggregate replacement. The strength and flexural behavior of concrete samples were studied using compression test and two-point loading tests. The capacity of the objects framed based on actual concrete and secondary product based concrete were evaluated with standard tests. Five sequence of mixing in concrete proportion were organized by means of SCBA restore cement by 0, 5, 10, 15, 20 and 25% by weight of cement and its 14 & 28 day strength were found out and the other mix with constant SCBA and varying percentage of Copper slag were prepared with 40, 45, 50, 55 and 60 % of copper slag for fine aggregate the 14 & 28 day strength were found. Flexural behavior of SCBA and CS combination were found using RCC beams. It has been engaged that SCBA and CS are better substitute for cement and fine aggregate.

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.

Sugar cane bagasse ash (SBCA) is a fibrous waste-product of the sugar refining industry. It is generated as a combustion by-product from boilers of sugar and alcohol factories. This is composed mainly by silica and this by-product can be used as a mineral admixture in mortar and concrete. This waste product is already causing serious environmental pollution which calls for urgent ways of handling the waste. On the other hand, the boost in construction activities in the country created shortage in most of concrete making materials especially cement, resulting in an increase in price. This study examined the potential use of sugarcane bagasse ash as a partial cement replacement material. In this paper, Bagasse ash has been chemically and physically characterized, in order to evaluate the possibility of their use into concrete.

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.
