  • This research is a lab experiments that are replacing the normal concrete conventional mix design with SNI on the characteristics of SCC. SCC or Self Compacting Concrete is an innovation in concrete construction technology today that uses the added material (admixture) to produce high-performance concrete with high workability value but it does not reduce the quality of the concrete. In this study, we want to know the effect of the addition of a chemical added superplasticizer "Protacon SP 29" of the concrete compressive strength and the characteristics of SCC with the quality of the plan of 350 Kg / cm2. Superplasticizer given in five doses of variation (0%, 1%, 1.3%, 1.6%, and 1.9%) to change the value of a normal slump to slump flow. Flowability testing method with SCC concrete-Cone Slump Test in fresh condition and compressive strength tests at the age of 7, 14, and 28 days. The results show a state of self-compactibility SCC superplasticizer achieved at all levels are given. Workability level flow (workable) SCC superplasticizer levels increased in accordance addition, SCC compressive strength increased as the addition of superplasticizer levels, and a decrease in dose variation of 1.9%. SCC optimal condition is reached at a level of 1.6% superplasticizer. Keywords: Concrete SCC, Admixture, flowability, Concrete Compressive Strength
