Concrete is a building structure whose development is relatively fast because it is an important part of development. Shells of keong sawah , which are pests for rice plants, can also be used as an added material in making concrete because they contain a large amount of calcium carbonate. This study aims to determine the effect of adding shells of keong sawah on the compressive strength of concrete with a variation of 0% and 15% on the weight of cement. This research was conducted using a cylindrical concrete specimen with a diameter of 15 cm and a height of 30 cm. The results showed that the addition of 15% powder shells of keong sawah had an increase in compressive strength, namely 31.1 MPa when compared to the 0% variation with a compressive strength value of 25.6 MPa. It can be concluded that in this study the addition shells of keong sawah 15% by weight of cement can increase the compressive strength of the concrete.
