Abstract

Making cement produces carbon dioxide (CO2) gas which results in the greenhouse effect. To reduce the use of cement, alternative materials are examined. One of the raw materials for making cement is limestone. Limestone is a sedimentary rock mainly composed of calcium carbonate. Blood clams (Anadara Granosa) are tried to replace cement because they have a high calcium carbonate mineral composition. Blood clams are crushed into powder and filtered using No.325 filter. Cement is replaced by weight by 5%, 10%, 15%, and 20%. Mortar specimens in the form of cubes with a size of 5 cm. Mortar compressive strength test was carried out at 7 and 28 days. Anadara Granosa powder reacts very weakly with water and increases the initial compressive strength of the mortar. The results of Anadara Granosa mortar compressive strength test at 7 days were higher than normal mortar. The most efficient composition is indicated by cement replacement of 20%.
