Abstract

Concrete is the main material for construction which is widely used throughout the world. However, with the increase in the use of concrete from time to time which causes the amount of available resources to decrease and will also disturb the environmental balance, an alternative that can be used to overcome this is to get environmentally friendly concrete which reduces the use of cement utilizing the results of industrial wastes. One of them is the utilization of oil palm shell ash waste. Palm shell ash is expected to be used as an additive to the concrete mixture. In this study, palm kernel shell ash was used as an additive to cement with a mixture of 0%, 3%, 6%, 9% by weight of cement. The number of test objects is 3 cylinders for each variation of the mixture. The type of test carried out is in the form of the compressive strength of the concrete and the observation of the test object is carried out at the age of 7 days, 14 days, 21 days, and 28 days. From the research results, it was found that the increase in the value of the compressive strength of concrete on the variation of the addition of palm shell ash waste as an added material to cement to create quality and environmentally friendly concrete.

Abstract

 Penggunaan pecahan keramik pada beton Normal merupakan langkah untuk pemanfaatan bahan pecahan guna untuk menggantikan sebagai bahan pengisi atau agregat kasar pada campuran beton. Penelitian ini dimaksudkan untuk mengetahui pengaruh penggunaan pecahan keramik sebagai pengganti sebagian agregat kasar pada beton normal, dengan membandingkan kekuatan antara beton normal dengan beton yang telah di campurkan sebagian pecahan keramik pada agregat kasarnya. Manfaat yang dapat diperoleh dari penelitian ini adalah dapat diketahui pengaruh penggunaan pecahan keramik sebagai pengganti sebagian agregat kasar pada beton normal, Pengujian meliputi uji kuat tekan. Mutu beton normal yang direncankan f’c = 22,5 Mpa. Dari hasil penelitian didapat nilai kuat tekan karakteristik Beton Normal sebesar f’c = 23,22 Mpa pada umur 28 hari dan beton dengan menggunakan pecahan keramik sebagai pengganti agregat kasar dengan variasi campuran 10% sebesar f’c = 16,44 Mpa pada umur 28 hari, variasi 20% sebesar f’c = 13,3 Mpa pada umur 28 hari, dan variasi 30% sebesar f’c = 11,3 Mpa pada umur 28 hari. Didapat hasil semakin besar variasi pecahan keramik mutu beton semakin turun.
