Abstract

One of the cases of human intervention in environment is vast variations in making parts of the land surface impervious, followed by changes in the hydrologic cycle. POROUS CONCRETE is an especial type of highly pervious concrete, compatible with the environment, and could be used a method to increase surface infiltrate and reduce urban runoff. In the present experimental research, to improve the performance of this type of concrete, effect of adding lightweight PUMICE and PERLITE (0.6-1.2 mm), and adding 10% fine grains to the samples, was investigated. In this respect, the effective parameters for using POROUS CONCRETE in URBAN RUNOFF SYSTEM, such as compression strength, hydraulic conductivity and porosity of the samples were measured. Analysis of experimental results was performed by using SAS 9.4 software at 95% confidence level. Results showed that adding fine grains to POROUS CONCRETE increases compression strength and reduces hydraulic conductivity and porosity. Addition of lightweight PUMICE increases compression strength and reduces hydraulic conductivity and porosity of POROUS CONCRETE. But, lightweight PERLITE reduced all three parameters of hydraulic conductivity, porosity and compression strength. In general, lightweight PUMICE, which has higher density and more pore space in its structure with respect to PERLITE, had better performance.
