A Study on Effect of Bagasse Ash in the Properties of Recycled Aggregate Concrete

Raghavendra S, Akshatha B A, Yashwanth M K, Pramod K

Abstract: The study presents a replacement of natural coarse aggregate (NCA) by recycled coarse aggregate (RCA) and cement by bagasse ash. The aggregate obtained from the construction and demolition waste for making a new concrete will have to give better stability same as concrete prepared by using virgin aggregate. Usage of recycled coarse aggregate in concrete is helpful for ecological protection, in other hand RCA will be material used in future. Bagasse ash is an agricultural or industrial waste by sugarcane milling process. Bagasse ash got cementitious property so it can be replaced with cement. In this project main aim is to evaluate the physical properties of both RCA and bagasse ash for M20 grade of concrete. NCA is replaced with 20 %, 30 % and 40 % of RCA and replacement of cement with 5 %, 10 %, 15 % and 20 % bagasse ash with 30 % RCA. The mix proportion and water cement ration of 12.43.9 and 0.45 used with 1 % super plasticizer (SP). The rheological property of concrete like slump cone and hardened properties like compression strength and split tensile strength for 7 and 28days and flexural strength test for 28days of curing was conducted. Durability and micro structural analysis like scanning electron microscope (SEM) also presented in the work. The results shows from hardened properties strength increased up to the replacement of bagasse ash 10 % with 30 % recycled aggregate
