Experimental evaluation of the effect

Abstract:

Pervious concrete is a special type of concrete designed to achieve better water flow and ventilation properties compared to traditional concrete. This concrete is widely used in various fields, such as storm water management and flood mitigation. In this research, permeable concrete was produced without fine materials. The samples contained aggregates of different gradations marked A, B, C, D and E with a fineness modulus of 3.21%. They were tested for compressive strength, density, infiltration rate, and porosity. The results indicated that the best mix of permeable concrete was obtained using the aggregate gradation from group E. A good relationship was observed between the aggregate gradation and compressive strength, density, infiltration rate, and porosity, as shown in the research. The average compressive strength at 28 days for the pervious concrete was 12.01 Mpa, and the density obtained for the gradation of group E was 1912 kg/m³, with an infiltration rate of 36474 mm/hr and a porosity of 18.43%. Libya, located on the Mediterranean Sea, is a country susceptible to flooding in certain areas, highlighting the importance of this research.
