Abstract:

Pervious concrete is significantly different to that of conventional concrete as it has the ability to allow water to percolate through it large sized pores. This unique ability presents many environmental benefits such as minimising storm water run-off, recharging groundwater and reducing the heat absorption in the pavement. This paper reports the results of an experimental investigation into the use of supplementary cementitious materials on the properties of pervious concrete (compressive strength, stiffness and water permeability) having the porosity of about 20%. The investigation considered four mixes with the following combinations of cement and supplementary cementitious materials, by weight proportion: (a) 100% cement; (b) 75% cement and 25% fly ash; (c) 92.6% cement and 7.4% silica fume; and (d) 84.2% cement, 8.2% fly ash and 7.6% silica fume. The results showed that the cement replacements with supplementary cementitious materials had improved the compressive strength, reduced modulus of elasticity and decreased the water permeability of pervious concrete with fixed porosity.
