Abstract: | Self-Consolidating Concrete (SCC) is a mixture that can be compacted into every corner of formwork without vibrating compaction. The method for achieving self-consolidating involves not only deformability of mortar, but also resistance to segregation between coarse aggregate and mortar when the fresh concrete flows through reinforcing bars. Many projects have been done using SCC with Densified Mixture Design Algorithm (DMDA) method in Taiwan. In this study, the method can create high density with low water and cement content to achieve the high cement strength efficiency. The stability can be controlled when the water cement content ratio is higher than 0.42, water content is around 160 kg/m3 and cement content is less than f’c/20 by using Rice Husk Ash (RHA). And then the physical density, flowability, and homogeneity can be achieved. Fresh properties of concrete in this study shows excellent flowability and passing ability without bleeding or segregation. In 28 days after casting, the compressive strength and splitting tensile concretes shows good result, this indicate that the SCC had good strength performance. |
