This paper presents the technical feasibility of using ash in mortars, from burning sugarcane bagasse, to generate power as a mineral admixture. The sugarcane bagasse ash (SCBA) underwent chemical characterization and x-ray diffraction tests. The milling of the material was studied, together with the composition of the mortars containing the SCBA at 3%, 5%, 8% and 10% ratios by weight, as partial replacement of fine aggregates. The mechanical properties were studied by compressive and diametral tensile strength tests. Some properties related to the durability of the material were also studied, such as drying shrinkage, capillary absorption and accelerated reactivity. The work was performed using low pozzolanic activity SCBA. However, the results indicate that it is possible to use SCBA as partial replacement of fine aggregates in the production of mortars.

The use of cement as a main binding material in the field of civil engineering is no doubt at the next level due to growth in urbanization. It is mainly used to make cement mortar, concrete, and other composite construction material. The extensive use of OPC in the construction industry has caused increment in the production of CO2 at atmosphere. This has deteriorated the environment and has urged everyone to study and research the sustainable progress by using different waste products as replacement in concrete and mortar. Therefore, the purpose of this study was to investigate the strength performance of cement mortar containing Sugarcane Bagasse Ash (SCBA) and Rice Husk Ash (RHA) as a Cementitious Material. In this study, we have substituted the cement with different 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 were examined by casting 36 standard cubes of 50mm size and cured for 3, 7 and 28 days. Test outcomes indicated that the flowability of mortar paste kept on decreasing with the increase in partial replacement by SCBA and RHA. As we have fixed the water cement ratio for all type of mix i.e., 0.5. From the outcomes of Density and Compressive Strength of Cubes cured in plain water, we come to know that as % replacement was increasing the density and compressive strength of cubes cured was reducing. For Compressive Strength, it was found that at each specified day, the compressive strength of cubes up to 10% 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 cubes has the highest values for all % of replacement.
In the present age the waste generated from industries such as sugarcane ash and marble waste is the huge concern for the environment, health, and cause for land filling. Recycling of such wastes and using them in construction materials appears to be viable solution not only to the pollution problem but also the economical option in construction. Incorporation of supplementary cementitious materials in mortar is necessary for sustainability. Supplementary cementitious materials are not only sustainable but also mechanical and durability properties of mortar. In this study sugarcane bagasse ash is incorporated as replacement of cement and granular marble as a replacement of fine aggregate in mortar. The levels of replacement of cement by sugarcane bagasse ash are 5%, 10%, 15%, 20% and25% and marble granular are 10%, 20%, 30%, 40%, 50%. The properties which are determined and compared in this study are workability, 7, 14 and 28 days compressive strength. The present study investigates the effect of pozzolanic material in mortar and hence improving the strength of mortar. This work evaluates the performance of Sugarcane Bagasse Ash (SBA) as a partial replacement of cement in mortar and also replaced with granular marble as a fine aggregate. In this project the SBA percentage is with different replacement of granular marble. The strength properties of mortar compared with the above varying percentage and the result on which it gives maximum strength is found out.
The cement industry is one of the largest embodied energy consuming and CO 2 emitting industry. It is found that to produce one kg of cement, it requires 4.2MJ of energy and liberates about one kg of CO 2 which is one of the important greenhouse gases as the global warming reason. The partial replacement of ordinary Portland cement by agricultural waste is an alternative solution for decreasing the CO 2 emission and to minimize the embodied energy of cement. In this study, the effect of sugar cane bagasse ash from three different sources, i.e. from Pandavpura, Nanjangud and Kuntur were collected. The bagasse ashes were ground until the particles retained on a 150µm sieve.The physical and chemical properties of the samples were tested. The tests conducted on the cement mortar are the flow table test and compressive strength test at 0, 10, 15, 20 and 25% replacement of cement by weight with different water cement ratios of 0.3, 0.35 and 0.4. From the experimental results it was found that water demand for the mortar increases with increasing percentages of bagasse ash due to larger particle size and high porosity of bagasse ash. It was also observed that from all the sources an average strength of 100% 108%, 101%, 97% and 94% were attained for 0, 10, 15, 20 and 25% replacement of cement by bagasse ash at 28 days.
Investigation on Control Burned of Bagasse Ash on the Properties of Bagasse Ash-Blended Mortars
Materials
In recent years, partial replacement of cement with bagasse ash has been given attention for construction application due to its pozzolanic characteristics. Sugarcane bagasse ash and fine bagasse particles are abundant byproducts of the sugar industries and are disposed of in landfills. Our study presents the effect of burning bagasse at different temperatures (300 °C and 600 °C) on the compressive strength and physical properties of bagasse ash-blended mortars. Experimental results have revealed that bagasse produced more amorphous silica with very low carbon contents when it was burned at 600 °C/2 h. The compressive strength of mortar was improved when 5% bagasse ash replaced ordinary portland cement (OPC) at early curing ages. The addition of 10% bagasse ash cement also increased the compressive strength of mortars at 14 and 28 days of curing. However, none of the bagasse ash-blended portland pozzolana cement (PPC) mortars have shown improvement on compressive strength with the a...

Sugarcane bagasse ash is a byproduct of sugar factories found after burning sugarcane bagasse which itself is found after the extraction of all economical sugar from sugarcane. The disposal of this material is already causing environmental problems around the sugar factories. 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 study, bagasse ash sample was collected from Wonji sugar factory and its chemical properties were investigated. The bagasse ash was then ground until the particles passing the 63μm sieve size reach about 85% and the specific surface area about 4716 cm2/gm. Ordinary Portland cement and Portland Pozzolana cement were replaced by ground bagasse ash at dif erent percentage ratios. Normal consistency and setting time of the pastes containing Ordinary Portland cement and bagasse ash from 5% to 30% replacement were investigated. The compressive strengths of dif erent mortars with bagasse ash addition were also investigated. Four dif erent C-35 concrete mixes with bagasse ash replacements of 0%, 5%, 15% and 25% of the Ordinary Portland cement were prepared with water to cement ratio of 0.55 and cement content of 350kg/m3 for the control mix. The test results indicated that up to 10% replacement of cement by bagasse ash results in better or similar concrete properties and further environmental and economic advantages can also be exploited by using bagasse ash as a partial cement replacement material.

Effect of use of Bagasse Ash on Strength of Concrete
With increasing demand and consumption of cement, researchers and scientist are in search of developing alternate binders that are ecofriendly and contribute towards waste management. The utilization of industrial and agricultural waste produced by industrial processes has been the focus on waste reduction. One of the agro waste sugar cane bagasse ash (SCBA)which is a fibrous waste product obtained from sugar mills as byproduct. Juice is extracted from sugar cane then ash produced by burning bagasse in uncontrolled condition and at very high temperature. In this paper SCBA has been chemically and physically characterized and partially replaced in the ratio of 0%, 10%, 15%, 20%, 25% and 30% by weight of cement in concrete. The properties for fresh concrete are tested like slump cone test and for hardened concrete compressive strength at the age of 7,28,56 and 90 days. The test result indicate that the strength of concrete increase up to 15% SCBA replacement with cement.

The current study presents the effect of pozzolanic material in concrete and its influence on the improvement of concrete strength characteristics. Bagasse is a fibrous waste product of the sugar refining industry made from sugar cane. Aluminium ion and silica are the major components of bagasse ash. Sugar Cane Bagasse Ash (SCBA) is used to partially replace the cement in concrete, in the range of 0%, 10% and 20%. Strength characteristics such as compressive strength, spilt tensile strength and flexural strength are evaluated and durability test is conducted. The results obtained are compared with conventional concrete. As the SCBA is increased from 0 to 10% the 28 days compressive strength values of M15, M30 and M50 mixes increase by 5.74%, 7.32% and 7.07% respectively. The split tensile strength values of M15, M30 and M50 mixes increase by 22.6%, 18.43% and 8.41% respectively. And the flexural strength values of M15, M30 and M50 mixes increase by 5.48%, 22.4% and 18.07% respectively. Hence the replacement of cement by SCBA up to 10% can be considered without compromising the strength properties. Durability study proves that the reduction in the compressive strength and loss of weight increases with increase in SCBA.
