In this study brief that effect the RHA and SF when replacement on cement with some of ratio of sand aggregates with polypropylene fiber (PPF). Use RHA to improve the mechanical properties for engineered cementitious composite (ECC) with rate of silica fume. ECC is new type of cement it improves the ductility; tensile strength also can repair. This experimental confers on high tenacity, shrinkage, compressive strength, and cracking load. In addition will add polypropylene fiber (PPF). Important things in this study to found best replacement of RHA with SF to get good condition of mechanical properties. And superplasticizer is added to the concrete mixture to make it smooth and easy to form. Mix proportion that replacement with Sf and RHA can showing as SF05%, RHA05% + SF 10, RHA10 + SF15, RHA15 + SF20%, RHA10% + SF25%, RHA05% + SF30%, RHA0%. Using silica fume to resistance of chloride, sulfate attack, corrosion currents and acids that can make concrete high crack resistance and high-grade concrete also can change of strength to make it high strength early.
