Abstract: Plain concrete is widely used as a building material. But plain concrete possess low tensile strength, low ductility and durability when compared to blended concrete. The environment is rapidly effected due to energy consumption and CO2 emission during cement production. To reduce the environment effect, Ground granulated blast furnace slag (GGBS) is used as a binding material in plain concrete which in addition improves strength, durability, workability and reduces the risk of sulphate attack and acid attack etc., simultaneously glass fibers are also added to possess high ductility in blended material (GGBS). In this paper, ductility, durability and flexural strength are the main parameters. Experimental work is conducted on M30 and M40 grade of concrete by replacing cement with GGBS by 60% and 0.4% of glass fibers are added by volume of concrete. Durability is age dependent parameter which is observed in curing with sulphate solution and acid solution for 30 days in cubes. Ductility of concrete by stress-strain behavior in cylinders. Flexural strength is assessed through load-deflection curve in beams. From the study, it is observed that use of blended concrete achieve more compressive strength, durability, ductility and flexural strength compared with conventional concrete.
Keywords: Durability, Flexural Strength, Glass Fiber and Ground Granulated Blast Furnace Slag (GGBS).
