| AbstraAbstract Self-compacting concrete (SCC) is a special type of concrete that can flow through intricate geometrical configurations under its own mass without external or internal vibration or segregation. The objectives of the research work were to evaluate the effects of filler types (silica fume and limestone dust) and high- range water- reducing agent, (HRWRA, superplastizier-type Sikament -163) on the workability and splitting tensile strength of SCC. The experimental results showed the using silica fume and limestone dust in Self-compacting concrete led to a considerable improvement in splitting tensile strength. As the percentage of limestone powder and silica fume increases, the workability properties of SCC slightly decreased with increases in splitting tensile strength. The workability properties of SCC for all the replacements satisfy the recommended values given by specifications.
