Abstract: The main purpose of this investigation is to study the behavior of rigid pavement (concrete) which occurs when cementing waste material (GGBS) and steel fibers are added and to compare with normal concrete of M40 grade. For this study, concrete cubes and beams were produced of five partial GGBS replacement ratios (10%, 20%, 30%, 40% and 50%) with constant water-cement ratio (0.37) and cement dose of 486 kg/m3 . To keep a constant workability, super plasticizer was used in concrete. The cubes and beams were tested at the age of 7, 28 and 56 days with continuous water curing condition. The comparison between normal concrete, GGBS concrete and with steel fiber concrete was made. After testing it was found that at 30% GGBS replacement we can get M40 strength of concrete. But flexural strength decreases by increasing percentage of GGBS so that to increase in flexural strength steel fibers of two different aspect ratios (7560 & 7530) was used. Steel fibers were added in concrete by 1% of total weight of concrete with different proportions. Thus the compressive and flexural strength reached up to considerable limit.

Keywords: GGBS, Steel Fibers, concrete.
