Performance of SCC Concrete with Additional Materials of Rice Husk Ash

Concrete with high ductility, workable, high strength, easy to flow without compaction, and durable is a concrete need in the future. Concrete with this quality, one of which is to make self-compacting concrete (SCC). This paper reports performance of self compacting concrete (SCC) containing rice hush ash. Rice husk ash is waste from burning rice husks. The purpose of this study was to determine the performance of SCC concrete with the addition of rice husk ash. SCC specimens were made using rice husk ash (RHA) and SCC without rice husk ash (NRHA). The specimens were made with water cement ratio 0.30. Superplastisizer used is a type Naptha 511P. The result indicated that the workability of SCC containing rice hush ash (RHA) more workable compare SCC without rice hush ash (NRHA). The initial setting time of SCC with rice hush ash more slowly compare SCC without rice hush ash. The compressive strength, flexural strength, and tensile strength of SCC RHA mor higher compare SCC without RHA (NRHA). The tensile strength value of RHA and without RHA concrete meets the tensile strength requirements of RSNI T-12-2004.
