Experimental Investigation on the behavior of basalt fiber-reinforced concrete beams with partial replacement of cement by ground granulated blast furnace slag(GGBS)

Abstract

The construction industry has seen a growing demand for cementitious compound, which is a primary building material. Traditionally, cementitious compound has been made using heavy materials, with steel being a popular reinforcement option. However, in recent years, there has been a trend towards reducing the amount of steel used in structures, and instead, Basalt Fibre Reinforced Polymer (BFRP) rods are being utilized. This study aims to investigate the behaviour of reinforced cementitious compound by adding BFRP bars as reinforcement and partially replacing cement with Ground Granulated Blast Furnace Slag (GGBS) in M50 grade cementitious compound. Various ratios of GGBS (0%, 20%, 40%, and 60%) were used to partially replace the cement content, and the compressive resistance, split tensile resistance were tested after 7, 14, and 28 days of curing. The cementitious compound with a 40% replacement of GGBS demonstrated raised resistance in compression resistance, split tensile resistance, and flexural resistance
