AbstractThe porous concrete applications and the process of production in different ways depending on the replacement of fine or coarse aggregate components of research important topics, The study dealt with production pervious concrete by depending on normal concrete by removing fine aggregate by four percentage by weight (25%, 50%, 75%, 100%), as was the work of trail mixtures of concrete for a reference mix of were depended mixture the weight [1:1.5:3] with a ratio (W/C) is equal to (0.40), which recorded the highest compressive strength of age (7) days, by the results tests show that the increased rate of removal of fine aggregate contributed to reduce the strength and density with the increase in porosity and permeability and absorption, as less density obtained is (1756.2)kg/m3 remove the fine aggregate by (100%), which gives less strength to compressive (14.28)MPa and the highest value for porosity (24.81%), as were better strength to compressive, splitting tensile, and bending are (36.77MPa, 4.28MPa, 4.4MPa), respectively to the proportion of removing fine aggregate (25%) compared to the reference mixture.
