چکیده انگلیسی
Using pervious concrete (PC) as a pavement material in low-volume road applications has gained great importance since its positive environmental benefits. The paper presented herein addresses the prospective use of acidic pumice aggregate in pervious concrete. At a constant water/cement ratio of 0.30, two control concretes were produced with only crushed stone aggregates with cement contents of 300 and 420â¯kg/m3, respectively. Thereafter, the acidic pumice were replaced with the crushed stone at 10%, 20%, 30%, 40% and 50%, respectively by total aggregate volume. A total of 12 pervious concretes (PC) were produced and tested for the compressive, splitting tensile, and flexural strengths as well as the total void ratio and permeability at 28 and 90â¯days. Additionally, the surface abrasion resistances of PCs incorporating pumice were tested at 90-day. Test results have revealed that the PCs incorporating pumice had better water permeability and surface abrasion resistance, irrespective of the replacement level. However, the compressive, splitting tensile and flexural strengths of PCs decreased with increasing the replacement level of pumice.
