PENGARUH PENAMBAHAN ABU SEKAM PADI TERHADAP KUAT TEKAN BETON

Abstract

Concrete is a very important construction material in today's infrastructure development. Therefore, efforts are needed to increase the compressive strength of concrete. Meanwhile, rice husk ash is an agricultural waste that is often found in this country. By adding rice husk ash to concrete, it is hoped that the concrete will have good compressive strength. In this study, rice husk ash variations of 0%, 2%, and 7.5% were used. Meanwhile, the maintenance age for concrete compressive strength is 7 days and 14 days. From this research, the maximum concrete compressive strength was obtained at 23.6 MPa for normal concrete and concrete mixed with 7.5% rice husk ash at a curing age of 14 days. Meanwhile, for concrete mixed with 2% rice husk ash, the compressive strength value at a curing age of 14 days decreased to 21.1 MPa.
