High early strength of slag based fiber reinforced concrete

Abstract

The experimental investigation achieved the high early strength of fiber reinforced concrete by adding slag (GGBS), rapid hardening admixture, and steel fibers. This concrete is done curing for seven days and followed by hot air oven curing for four hours as per different mixes. Tests such as destructive and non-destructive test have been performed. During the testing of the cube which is cured for seven days has achieved the high compressive strength of 42.24 N/mm2 for M25 Grade of concrete.
