Comparative Study on the Compressive Strength Performance of Pumice with 30% GGBS and Metakaolin with Conventional Concrete

Manoj Sasikumar and Lakshmi Thangasamy

Abstract

The scope of the paper is to compare the conventional concrete by employing a mix of M30 grade concrete, a novel pumice aggregate is used to partially replace the coarse aggregate to create lightweight concrete. Both the coarse and fine aggregates are new pumice stone. The curing dates of 28 days were used to make a group of 6 cubes. As usual in our concrete, all groups are composed of 60% cement mix, 30% GGBS (Ground granulated blast furnace slag) modified, and 10% metakaolin. As per the curing date for 28 days, a group of 18 cubes was made. A total of 36 cubes were built in two groups in order to calculate the compressive strength. For typical concrete of grade M30, the average compressive strength test result at 28 days was 30.28 N/mm2. Concrete’s noteworthy 34.53 N/mm2 compressive strength test result at 28 days for group I and M30 grade concrete in 18 cubes using innovative pumice aggregate stone and partial substitution of GGBS and metakaolin in cement weight. Two-tailed tests had a result of p = 0.005, which was lower than p = 0.05. A statistically significant difference exists between the two groups as a result. The 28-day M30 grade concrete compressive strength, concrete employing novel pumice aggregate compressive strength test results, and partial substitution of GGBS and metakaolin by weight of cement.
