Abstract: |
This paper presents the key properties of freshly mixed self-consolidating concrete (SCC) incorporating rice husk ash (RHA). Air-entrained SCC mixtures were produced based on the water/binder (W/B) ratios of 0.30–0.40. RHA was used substituting 0–30% of cement by weight. The fresh properties investigated were ï¬lling ability, passing ability, segregation resistance, air content, and unit weight. The effects of RHA and W/B ratio on these properties were observed. Test results revealed that the fresh properties were signiï¬cantly influenced by the W/B ratio and RHA content of concrete. RHA also affected air entrain- ment and decreased the unit weight of concrete. |
