Durability Study of Lightweight Aggregate Concrete using Pumice Aggregate as Replacement of Coarse Aggregate

Abstract

Abstract

Lightweight concrete has less dead load as compared to the normal concrete. Most of the buildings are made in India using light weight aggregate/materials. In this experimental work, we need to focus on the light weight concrete using pumice aggregate and assessment of the result of compressive strength and reduction in dead load of the concrete. Four concrete mixes of M1, M2, M3 and M4 were prepared with the different replacement ratios (0, 15, 30 and 45%) of pumice aggregate with coarse aggregate respectively. Each set of concrete mix comprised of 9 cubes, tested at the age of 7, 14 and 28 days of curing period. It is concluded that with the increase in replacement of pumice stone by 15, 30 and 45%, the compressive strength decreases by 6.12, 14.25 and 22.84% respectively at 28 days of curing period.
