The Effect of Different Cement Types on Pervious Concrete

Pervious concrete (also known as porous concrete, permeable concrete, no fines concrete, and porous pavement) is a high-porosity concrete used in concrete flatwork applications that allows water from precipitation and other sources to pass directly through, reducing runoff and allowing groundwater recharge. Coarse aggregates are used in pervious concrete, with little or no fine particles. The aggregates are then coated with concrete paste, allowing water to flow through the concrete slab. Pervious concrete has typically been utilized in parking lots, low-traffic areas, residential streets, pedestrian pathways, and greenhouses. This study shows the effects of cement types on both fresh and hardened concrete by using different cement types as the only variable in permeable concrete. CEMI and CEMII cement types are discussed for this study. The number of other components used in concrete, water, cement and aggregate is the same in both concretes. The water/cement ratio is the same for both concretes and is 0.34. The diameter and shape of the aggregate used in the concrete is very important for the protection of the hollow structure to be formed in the concrete. Therefore, 14mm limestone aggregate and 5mm sand were used as coarse aggregate. The amount of fine aggregate used is 10% of the coarse aggregate by mass. In this study, the use of fine aggregate was preferred because it was aimed to obtain high compressive strength. Experimental results showed that concrete using CEMI cement in general had superior properties compared to concrete produced using CEMII cement.
