Abstract :

This paper presents the experimental investigation conducted on silica fume roller compacted concrete (SRCC) to evaluate the compressive strength, split tensile strength and modulus of rupture or flexural strength properties. In the preparation of silica fume roller compacted concrete, cement was replaced at various percentage levels such as 5%, 7.5% and 10% by weight of cement have been added to RCC. Tests were performed to determine workability when RCC is in fresh state and strength properties when RCC is in hardened state. Workability tests like compaction factor test, vee–bee test and slump test were conducted. Strength tests like compression strength, split tensile strength, flexural strength at 3 Days, 7 Days, 28 Days. Experimental investigation revealed that significant increases in strengths were observed in SRCC with increase in silica fume replacement. And workability of concrete was decrease with increase in silica fume.
