Strength Comparison of Conventional Paver Block by Partial Replacement of Fly Ash and Bottom Ash

Abstract

The experimental work is carried out on waste materials like, fly ash and bottom ash used in concrete. These waste materials will partially replace with various percentages of 0 to 25% with increment is 5% by weight fly ash in cement and bottom ash in fine aggregate. The compressive strength of concrete will test at 3, 7 and 28 days. In this experimental investigation partially replaced fly ash and bottom ash will obtained that only 20% replacement done both fly ash and bottom ash. The compressive strength of partially replaced fly ash and bottom ash concrete have 17.40% and 25.78% higher strength than the conventional concrete, both fly ash and bottom ash partially replaced in concrete will get 32.15% higher strength than the conventional concrete respectively.
