Mechanical Characteristics Of Concrete With The Addition Of Integral Waterproof Using Local Aggregate East Kalimantan

Abstract Nowadays, there are various ways to deal with leaks in concrete. One way that is often used provide a waterproofing or layer on the surface of floor wall. Along technological developments, research quality concrete continues be improved. them use Concrete Integral waterproofing, which mixture added integral minimize water penetration into concrete, thereby increasing concrete’s impermeability and protecting against leakage. The purpose this study was determine effect adding compressive tensile strength optimum level addition waterproofing. aggregates Palu coarse aggregate Kalimantan local fine utilize natural resources East Kalimantan. Addition Waterproofing percentage 0%, 0.5%, 1% 2% cement weight. testing carried out at age 28 days by its mechanical properties, namely strength. Based results, for uses Mahakam aggregate, highest value 34.73 MPa, 2.38 MPa. And Sambera 30.91 1.5% 2.34 Mpa.
