A study on replacement of fine aggregates and cement

Abstract

This abstract is about the usage of foundry sand instead of the fine aggregates, bagasse ash instead of cement. As cement also has some disadvantages with it like it has low tensile strength, its ability to resist deformation is very low, it is easily brittle. Cement is also considered to be one of the major sources which causes air pollution releasing a large amount of carbon in the atmosphere. So to replace cement such materials can be used as an alternative. Foundry sand is a natural fine aggregate which is obtained from the industrial byproducts. It was studied that by blending 30% of foundry sand with cement there was an increase in splitting tensile strength, compressive strength, and flexural strength as compared to the conventional concrete. Addition of this sand doesn’t affect its properties related to strength. Bagasse ash is a pulpy product obtained from sugarcane i.e., after the extraction of juice from the cane the squeezed parts are called molasses. In this research, Bagasse was used in the percentage of 30 % and 20% with the partial replacement of cement. Cubes were made by using the mortar which was prepared using the replacement materials. The mortar specimens were tested in their fresh and hardened stage of mortar to study the strength and durability of materials proportion in mortar.This abstract is about the usage of foundry sand instead of the fine aggregates, bagasse ash instead of cement.
