Abstract
Proper implementation of porous concrete pavements can have a resistance of more than 20 MPa, which in the pavement of parking lots, urban thoroughfares, as a drainage layer under the asphalt in cases where there is a need for drainage and water conduction, as well as in cases That the groundwater level is high is too much. Today, the concrete industry plays a very important role in the construction of human societies and is one of the most effective factors in concrete structures in the world. One of the several commonly used concretes is sponge concrete (porous), which is a mixture of coarse aggregate (sand), cement, water and sand in small quantities, which creates a void of 15-25%, which causes Water passes through this concrete. In this study, the optimal ratios of fine to coarse aggregate, amount and size of coarse aggregate, density, permeability, porosity and compressive strength of porous concrete were investigated.
