Pemanfaatan Limbah Kulit Kerang Sebagai Pengganti Sebagian Agregat Halus Dan Kasar Ditinjau Terhadap Kuat Tekan Beton K-225
The study of the effect of the use of shellfish waste as a substitute of some fine and coarse aggregate is due to shell waste is one type of artificial light aggregate, other than that the shell is a local material that is easy in the can and shell waste has not been widely utilized. The purpose of this research is to know the comparison of the results of the compressive strength of normal concrete with compressive strength of concrete that has been replaced some of its coarse and fine aggregate with shell waste in certain variants, is 25%, 30%, and 35% in fine aggregates and 10%, 15%, and 20% on the crude aggregate. The concrete compressive strength of the plan in this study is 225 kg/cm2. With 30 samples. The maximum concrete compressive strength is at a percentage of 35% fine aggregate added with 20% coarse aggregate with a compressive strength value of concrete of 296.10 kg/cm2, while the minimum compressive strength value of the concrete is at a percentage of 25% fine aggregate added with 20% coarse aggregate with a compressive strength value of 172.97 kg/cm2.
Keywords: fine and coarse aggregate, shell waste, concrete compressive strength
