Abstract
The use of pervious concrete pavement is significantly increasing due to the reduction of road runoff andabsorption of noise. However, this type of pavement cannot be used forheavy traffic due to a highamount of voids and consequently low strength of perviousconcrete. In this paper, rice husk ash(RHA) was used in order to strengthen pozzolaniccement paste and the effect of 0%, 2%, 4%, 6%, 8%,10% and 12% weight percentages asa cement replacement in concrete mixtures on the mechanical properties was studied.Moreover, 0.2% Vf of glass (where Vf is the proportion of fiber volume to total volumeofconcrete), 0.5% Vf of steel and 0.3% Vf of polyphenylene sulfide (PPS) fibers were usedto improve themechanical properties of the pervious concrete. Also, several water tocement (w/c) ratios were made andthen, physical and mechanical properties of hardenedconcrete, including porosity, permeability, compressivestrength, tensile strength andflexural strength were investigated.
