Abstract

In the last few decades, the use of Porous concrete to cover the sidewalks and pavements as an interface to collect the urban runoff has been increased. This system is economically more efficient than other runoff-pollution reduction methods. To design a runoff control system and reduce its pollution, it is necessary to determine the hydraulic and dynamic properties of the Porous concrete (with and without additives). In this research, the effects of cement type (2 and 5), water to cement ratio (0. 35, 0. 45 and 0. 55), fine grains percent (0, 10 and 20%), the type of additive (pumice, industrial pumice, perlite and zeolite), and the added additive percent (5, 10, 15 and 20%) on the physical properties of the Porous concrete (porosity, hydraulic conductivity and compressive strength), each with three replications, were investigated using robust design. Qualitek-4 software was also used to discuss the results. The results showed that to obtain the highest porosity in the mixing scheme of the Porous concrete, no fine grains, cement type 2 and 15% industrial pumice should be used, and water to cement ratio should be 0. 35. Also, the water to cement ratio of 0. 55, 0% fine grains, type 2 cement and 15% industrial pumice resulted in the highest value of hydraulic conductivity in the Porous concrete. Finally, the water to cement ratio of 0. 55, 20% fine grains, type 2 cement and 5% zeolite led to the maximum compressive strength. In general, it was not possible to reach a logical conclusion in this research with the least costs without employing the robust design.
