Abstract:
Porous concrete is made by mixing Portland cement, coarse aggregate, with or without fine aggregate, additives, and water. Concrete that uses white or colored cement creates a highly contrasting visual and enhances traffic safety. A study was carried out on porous concrete using white cement as a binding agent. There are 6 types of gravel/cement ratio by mass used, namely 4, 4.5, 5, 5.5, 6, and 6.5. There are 2 types of water/cement ratios used, namely 0.27 and 0.30. SicaCim concrete additives are used as chemical admixtures. The total test specimens were 36 pieces, and 3 pieces for each variation. The results show that increasing gravel / white cement ratio decreases compressive strength and increases porosity. Compressive strength of wcr 0.27 is smaller than wcr 0.30. Porosity of porous concrete in general with a wcr of 0.27 is greater than a wcr of 0.30. The effect of water cement ratio (wcr) and aggregate / white cement ratio is not too significant on the unit weight of porous co
ncrete.
