This study was conducted to optimize the variables involved in the performance of the pervious concrete using Central Composite Design (CCD) by Response Surface Methodology (RSM) Approach. The variables used in this study were water cement (W/C) ratio and sizes of coarse aggregate as the pervious concrete has no fines in it, later the responses permeability and compressive strength of the pervious concrete mixtures were recorded and analyzed using RSM the results shows the optimized values i.e., 0.34 water cement ratio and 10 mm size of aggregate that can be adopted to cast pervious concrete to attain the permeability of 4.41 mm/sec and compressive strength of 8 N/mm2.The optimized values are noted, using these values pervious concrete using bricks as aggregates were casted and tested after the curing period. The responses permeability and compressive strength was compared with the conventional pervious concrete.

摘要

This study was conducted to optimize the variables involved in the performance of the pervious concrete using Central Composite Design (CCD) by Response Surface Methodology (RSM) Approach. The variables used in this study were water cement (W/C) ratio and sizes of coarse aggregate as the pervious concrete has no fines in it, later the responses permeability and compressive strength of the pervious concrete mixtures were recorded and analyzed using RSM the results shows the optimized values i.e., 0.34 water cement ratio and 10 mm size of aggregate that can be adopted to cast pervious concrete to attain the permeability of 4.41 mm/sec and compressive strength of 8 N/mm2.The optimized values are noted, using these values pervious concrete using bricks as aggregates were casted and tested after the curing period. The responses permeability and compressive strength was compared with the conventional pervious concrete.
