Experimental investigation on the mechanical behavior of glass fibre-reinforced concrete with partial replacement of cement with silica fume

The construction industry has advanced to a great extent by using natural fibres and mineral admixtures in concrete taking sustainability into account. The addition of glass fibre at less proportion has shown some interesting values in terms of tensile behavior. Admixtures have mostly been used in concrete to support the development of work in the construction industry. Certain admixtures are required to get the intended effects out of the concrete. The paper revolves around the examination of the mechanical behavior of glass fibre-reinforced concrete (GFRC) with cement partially replaced by silica fume such as compression test and split tensile strength. Silica fume as an admixture is added to glass fibre-reinforced concrete in this paper in varying quantities to partially replace cement. Glass fibre 1% and silica fume at varied percentages such as 15, 20, and 25% have been used. The compressive strength increased by 13% and tensile strength by 40% in comparison with conventional concrete.
