Mechanical Properties of Self-compacting Concrete Made of Glass Fibre

Abstract

Self-compacting concrete (SCC) which is an extremely floatable, non-segregated concrete can reach easily at the congested formwork and covers the brace without any vibration. This present research work is focused on comparison of the mechanical properties of glass-fibre-reinforced SCC of grade M30. The mechanical properties of SSC like compressive strength, flexural strength, split tensile strength with different ages at 7 and 28 days are evaluated. During the experimental work, the workability is measured by slump flow test, T50 flow test, L-box test and V-funnel test. In this current experiment, long chopped glass fibres of size 12 mm are used to reinforce SCC. Replacement percentages such as 0.05, 0.10, 0.15, 0.20, 0.25 and 0.30% are adopted throughout the research programme. It is observed that at 0.20% replacement, mechanical properties show the better results than control mix and other replacement percentage. Load deflection curve of SCC beam reinforced with glass fibre shows better ductility.
