Abstract

This research uses stone ash waste from the stone crusher industry to preserve the environment. This material is an ingredient in making normal concrete. The use of stone ash as a substitute for sand is expected to increase the compressive strength in the planned slump and can optimize the use of rock ash waste to reduce environmental pollution that occurs. This study uses an experimental method with a total of 32 pieces of specimens. Each variation consists of 3 samples with a variety of fine aggregate levels of 40%, 44%, and 46%. The test object is a concrete cylinder with a diameter of 15 cm and a height of 30 cm. Test results for compressive strength at seven days for fine aggregate content variations of 40%: 22.25 Mpa; 44%: 24.30 Mpa; 46%: 17.08 MPa. Test results of compressive strength at the age of 14 days for variations in fine aggregate levels of 40%: 26.10 Mpa; 44%: 28.51 Mpa; 46%: 20.04 Mpa. Test results of compressive strength at the age of 21 days for fine aggregate content variations of 40%: 28.18 Mpa; 44%: 30.78 Mpa; 46%: 21.63 MPa. With these results, the Porous concrete produced can be used as preservation and maintain environmental protection. This product very cheap when compared to the original concrete, which calculated 22 U$ per square. The use of porous concrete has an impact on people's behavior that will preserve the environment, especially water content in the soil.
