| Abstract | This research is carried out to find the effect of various factors such as Silica fume content, fine aggregate content, water to cement ratio and aggregate to cement ratio on the hardened properties; compressive strength, flexural strength, permeability, porosity and surface abrasion of high strength pervious concrete. Two level full factorial design (2k) with center points is adopted to analyze the results where k is the number of factors choose. A constant amount of superplasticizer (ViscoCrete 10) which 0.8% by the weight of cement was used for the entire experiment process. 33 experiments were carried out and the obtained results were analyzed by Minitab17 software. Experiment results showed that the A/C ratio is the most influencing factors for all response, but for surface abrasion, fine aggregate content has a little more effect than the A/C ratio. All 33 mixes were confirmed to be pervious concrete with considerable percolation rate. The compressive strength of pervious concrete ranged from 5MPa to 37MPa and the flexural strength ranged from 1.3MPa to 6.1MPa. The highest strength was achieved by the mix with 16% Silica fume, 10% fine aggregate, 0.33 W/C ratio and 3 A/C ratio. The permeability of pervious concrete ranged from 1.3 mm/sec to 18.2 mm/sec. |
