Experimental Study On Increasing The Characteristics Of Porous Concrete With The Addition Of Silica Fume

Author(s)

Abstract
In the construction of road facilities and infrastructure, concrete or asphalt pavement is frequently used, which has the drawback of being impermeable. When the rainy season arrives, puddles or floods become more frequent as a result of the decline in water-absorbing areas. With the discovery of porous concrete, innovation is a solution to this problem; so in the following research, the authors will examine the addition of mineral admixture (Silica Fume) with proportions of 0%, 5%, 10%, and 15% in a porous concrete mixture that aims to improve the characteristics of porous concrete with the addition of mineral admixture (Silica Fume) so that a standard composition can be found and utilized in the construction industry. According to the study's findings, the variation containing 15% Silica Fume is the most effective at enhancing the characteristics of porous concrete. Where with a compressive strength of 21.327 MPa, which meets the minimum compressive strength requirements of porous concrete according to ACI 522R-10, which is at least 2.8 MPa, the permeability test result of 1.002 cm/s meets the requirements of ACI 522R-10, which is a minimum value of 0.14 cm/s, and the porosity test result of 15.605% meets the requirements of ACI 522R-10, which is 15-30%.
