Abstract
One of the innovations in the world concrete industry development is Self Compacting Concrete (SCC), which is known as concrete that can compact by itself. The material used in SCC differs from conventional concrete, for example, the reduction of amount and passing size 10 mm for coarse aggregate, the addition of fine aggregate amount, and the addition of quartz sand with grain size 50 - 650 μm to reduce hydration heat and increase the flow ability and workability on fresh concrete mixtures. In addition, chemical admixture with high-range water reducer (HRWR) type is used to reduce the water use and mineral admixture is also used in the form of rice husk ash as a substitution material for cement use. SCC is expected to reduce the cement use in concrete mixtures which is not environment friendly. This study used variations of w/c = 0.275, w/c = 0.300, and w/c = 0.325 and the rice husk ash by 0%, 5%, 10%, and 15% of the cement use. Flow ability test, and workability test were performed using test equipments such as slump cone test, V-funnel, and L-box to know the SCC criteria. After that, the concrete compressive strength test was performed at age 3, 7, 14, and 28 days with cylindrical samples with size 100x200 mm. The higher use of rice husk ash causes the value of flow ability and workability tends to decrease and the decrease of concrete density. The result of compressive strength test at age 28 days of SCC-10-0.275 mixture showed a significant increase of compressive strength of 70.528 MPa and the minimum compressive strength was 46.679 MPa for mixture SCC-15-0.325. Key words: Self compacting concrete, V-funnel, L-box, rice husk ash, flow ability
