Abstract :
Concrete is the most important and most widely used material in the construction world, either in the form of buildings, bridges, and roads. The concrete mixture consists of cement, sand, gravel, water and other added materials with a certain comparison. The use of the main mixed materials concrete can be replaced with other materials that are certainly qualified as concrete mixing material. Besides, many waste results in the community that can not be utilized to the fullest. Especially waste stone ash and rice husk ash. Then this research aims to use waste rice husk ash as a substitute for cement and ash stones as a substitute for fine aggregate on concrete mixing. The samples used are cylinder-shaped. Concrete is planned with FC ' 40 MPa with a comparison of waste of stone ash as much as 40% of the weight of sand, waste of paddy husk with variations as much as 0%, 5%, 10%, 15%, and 20% of the weight of cement. The test parameters are strong press, slump test, concrete absorption. For absorption testing conducted on the 28th day, while for strong testing concrete press done on day 7, 14, 28 and test results at the age of 28 days, strong press on normal concrete variation of 40.764 MPa with an absorption value of 7.860% and Value of slump 10.7 cm. Strong press optimum is found on variations of stone ash 40% and the waste of paddy husk of 10% by 43.029 MPa with absorption value of 9.936% and slump value 9.8 cm.
