A Comparative Study on Mechanical Properties of Basalt Fiber Reinforced Concrete with Partial Replacement of Cement with GGBS

Abstract

The Present work deals with the addition of Basalt Fibers in to concrete to inspect and compare the Compressive, Split Tensile and Flexural strength of Basalt Fiber Reinforced Concrete [BFRC] with plain M30 Grade concrete. In this experimental work the Basalt Fibers are chosen in four different proportions i.e. 0.5%, 1%, 1.5%, 2% & 2.5% respectively to the volume of concrete. Fibers of length 1.5 to 2cm were used in this study. Typically to improve the Tensile and Flexural strengths of concrete, fibers are introduced in to the concrete and it is named as fiber reinforced concrete. Fibers namely Steel, Carbon, Glass, Coir, Basalt.., are commonly preferred to use in concrete. In this work i have also studied the performance of basalt fiber reinforced concrete when the cement is partially replaced with Ground Granulated Blast Furnace Slag (GGBS).The replacement of cement with GGBS is done in two different percentages i.e. 30%, 40% respectively. The results have declared that the use of basalt fibers has significantly increased the flexural and tensile strength of concrete, but decrease in compressive strength of concrete. When the cement has replaced with GGBS the strength of the concrete has failed at 40 % respectively.
