Analisa Pengaruh Penambahan Sekam Padi Sebagai Bahan Campuran Pembuatan Paving Block

Abstract

Development in Indonesia is currently continuously improving, for infrastructure development such as pedestrian places, parking lots, and other facilities, it demands to be built both technically and in terms of the economy. Concrete brick mixture is a combination of the composition of the constituent materials. The characteristics and properties of the material will affect the design result. If it is associated with the development of the times which also results in an increase in waste, in addition to reducing environmental pollution, it can also be used as a mixture for making paving blocks. One of them is waste rice husks. Until now, rice is the main agricultural product in Indonesia. The method used in this study is testing materials at the Integrated Engineering Laboratory of Pahlawan Tuanku Tambusai University to find the effect of the value of adding rice husks as a mixture of making paving blocks on water absorption and compressive strength. Each of the variations used was 0%, 10% and 20%. The results showed that the 0% water absorption test had an average value of 11.46%, 10% had an average value of 16.14%, and 20% had an average value of 23.80%. And for the 0% compressive strength test at 28 days of age has an average value of 26.678 Kg/cm2, 10% has an average value of 33.137 Kg/cm2, and for 20% it has an average value of 16.007 Kg/cm2.
