Mechanical Properties of Rubberized Self Compacting Concrete Containing Silica Fume

Abstract:

The disposal of waste rubber produced each year is a critical issue for any country, because this material doesn't resolve easily and leads to more environmental pollution. Utilizing waste rubber in industry is an alternative for the disposal of this matter. In the present study 5%, 10% and 15% of coarse aggregate is replaced with crumb rubber by volume along with 5%, 10% and 15% silica fume as cement replacement by weight in self compacting concrete. There were several rheological tests carried out on fresh concrete such as slump flow test, T₅₀, J-ring, L-box and V-funnel test. Mechanical properties of specimens were also examined; compressive strength at 7 and 28 days of curing and modulus of elasticity and density of hardened cylindrical specimens at 28 days of curing.
