Pengaruh Substitusi Sandblasting Pada Campuran Beton Mutu Tinggi

High quality concrete is a type of that has been given special treatment, if no materials are added, it cannot always be obtained with conventional materials. The purpose this study was to determine the best sandblasting substitution composition in producing high concrete. method used design mixture SNI method, 42 MPa. results indicate for testing compressive strength at age 28 days, highest value 10% variation 49,163 MPa, split tensile sandblasted 4.789. flexural 6,399 MPa and modulus elasticity 22531,964 From concluded use as substitute fine aggregate showed an increase variations test, test
