Abstract

Along with the development that occurred in this era of globalization, the land where water can be absorbed is also decreasing so that it can result in an increase in the amount of surface water runoff and a decrease in groundwater reserves. To overcome this problem, the solution that can be done is to use pervious concrete where this level of concrete has a high permeability value. Pervious concrete is environmentally friendly concrete because it has high permeability and porosity values, so that water can enter the concrete layer. By using this concrete runoff surface water can be channeled to the ground so that groundwater reserves are maintained. However, most of the rainfall in Indonesia falls into the category of acid rain where it can damage pervious concrete. This research is about the effect of aggregate size, and variation of curing on the value of compressive strength, permeability and porosity. This study also discusses the durability of pervious concrete against H2SO4. There are three curing used in this research, namely, burlap sack, wrapping, and ambient. Meanwhile, the aggregate sizes used are 19-12.5 mm and 9.5-4.75 mm. From the results of this study the maximum compressive strength and density were found in the mixture of small curing wrapping aggregates of 8.3 MPa and 1801.42 Kg/m3. The maximum porosity and permeability values obtained in the ambient curing small aggregate mixture are 28.98% and 1.485 cm/second. From the durability test, the higher the concentration of H2SO4 the more it affects the decrease in the compressive strength value that occurs. At a concentration of 4% the decrease in compressive strength that occurs is the largest decrease.
