Abstract

This study investigates the usage of artificial aggregates made with bagasse ash, which is a by-product of bagasse cogeneration power industries where pulped sugar cane is used as a burning element and the final residue can be obtained in the form of fine powder. An attempt is made to produce light weight pelletized bagasse ash aggregates by pelletization technique. The usage of Bagasse ash aggregate in concrete as a partial replacement of natural aggregate has been examined. The concrete so produced is light weight in nature and the development of such concrete with light weight pelletized bagasse ash aggregates is to minimize the conventional aggregate which results in decreasing the self weight of the concrete along with to increase the efficiency of concrete as a structural material. In this Investigation M25 grade concrete with replacement of natural coarse aggregates by (0%, 20%, 50%, 75%, and 100%) bagasse ash aggregate is studied. The effect on strength properties such as compressive strength of cubes, spilt tensile strength of cylinders, flexural strength of beams, modulus of elasticity and in-plane shear strength through mode-II fracture test are studied.
