Abstract

Abstract The use of waste materials in concrete has increased rapidly nowadays which is used to increase the structural properties of the concrete at the same time waste recycle. Many studies show that the use of some waste materials reduced the brittleness and increased the mechanical properties of lightweight concrete. In this experimental paper, steel waste from industries is used in lightweight perlite concrete. Compressive test, flexural test and tensile test are performed to study the mechanical properties of 28 days reinforced lightweight perlite concrete. 0.5% and 1% in the volume were added to the mix. The results show that there was a significant improvement in the tensile and flexural characteristics of lightweight perlite concrete. At 0.5% compressive strength increases but decreases slightly at 1%, when compared to normal lightweight perlite concrete.
