Optimization of Mixing Proportions to Improve Strength and Hydraulic Performance in Pervious Concrete

The ever-increasing desire in pervious concrete is fuelled by its eco benefits, especially in eco water administration and city drainage systems. However, optimizing its mechanical durability while preserving suitable penetrability and porosity remains a crucial obstacle. This study examines the influence of mix proportions on the structural and water performance of previous concrete to distinguish a perfect mix design. Fifteen mix versions were assessed by changing the water-to-cement (W/C) ratio, aggregate-to-cement (A/C) ratio, and cement content. The conclusions show that a mix containing 440 kg/m3 of cement with a W/C ratio of 0.32 accomplished the largest compressive strength of 22 MPa while preserving operational penetrability. The findings propose that an ideal balance between mechanical and water properties can be accomplished through precise material proportioning and controlled compaction energy. These understandings provide a foundation for designing high-functioning previous concrete, making it a viable solution for eco infrastructure applications.
