| Abstract | In this study, the effect of cement content, coarse aggregate content, water to cement ratio, fine aggregate, fly ash and coarse aggregate size on the compressive strength, flexural strength, permeability and porosity of pervious concrete were investigated by using design of experiment. The design resolution with IV resolution design are chosen to perform the total number of runs 26-2 =16 in the experiment. Total six factors (cement content, coarse aggregate content, water to cement ratio, fine aggregate, coarse aggregate size and fly ash) are the factors used in performing DOE. The mechanical and physical properties of porous concrete such as compressive strength, flexural strength, permeability and porosity are carried out according to ASTM standards. The pervious concrete mixture was made with cement content (270-370 kg/m3), coarse aggregate content (1200-1665 kg/m3), water to cement ratio (0.3-0.35), fine aggregate (0-166.5 kg/m3), fly ash (0-70kg/m3), and coarse aggregate size (9.5 and 19 mm). The results showed that water to cement ratio effect the hardened properties of pervious concrete most. Cement content, coarse aggregate content and fine aggregate are also influenced on compressive strength, flexural strength, permeability and porosity of pervious concrete. With increase in water to cement ratio and decrease in coarse aggregate content led to reduce the permeability and porosity by increasing the compressive strength and flexural strength. The material proportions for different target values of properties (Compressive strength, flexural strength, permeability and porosity) at 28 days with minimum cost is obtained by optimization method. |
