【 摘 要 】

SFCCisoneoftheself-compactingconcreteinnovations. Withthepresenceoffiber,this concrete is not only famous for its own compaction process but also has good tensile strength and good ductility when compared to normal Self Compacting Concrete (SCC). Taking into account the environmentalandeconomicfactorsoftheuseofcementasamajorcomponentinthe manufactureofSFCC,thisresearchisinnovatingbyreducingtheuseofcementand replacingit with the use of silica fume. The silica fume variations usedin this study include 5%, 10%, and 15% with the use of 1% nylon fiber. Fresh properties testing including slump flow, T50, V -Funnel, and L -Box for silica fume variations were conducted in this study. Not only that, compressive strength, tensile strength and flexuralstrengthtesting are carried out to study the mechanical properties of the SHCC against silica fume variations. The results show that the use of silica fume variations will affect the fresh properties and mechanical properties of the SFCC concrete. The use of 5% silica fume in SFCC concrete is the optimum use to get the optimum compressive strength.
