Pengaruh Limbah Cangkang Kerang sebagai Pengganti Agregat Kasar terhadap Sifat Mekanik Beton
Abstract
The rapid development of infrastructure in Indonesia triggers the need for concrete materials which are
increasingly running out. Therefore, a replacement material is needed so that the use of conventional concrete
materials is not excessive, one of which is shellfish as a substitute for coarse aggregate. In this study, there are 72
specimens were made with a size of 150 x 300 mm divided into 3 tests with a concrete quality plan of f'c 30 MPa.
Shells are divided into 5 variations of shells as much as 1.75%, 2%, 2.25%, 2.5%, 2.75% and also normal concrete.
In the compressive strength & modulus test of 38.39 MPa and 29119.03. For testing the split tensile strength of
concrete, the highest value was obtained at substitution of 2% with a split tensile strength of 3.41 MPa.
