Abstract

Self-compacting concrete (SCC) is a flowing concrete mixture that is able to consolidate under its own weight. The highly fluid nature of SCC makes it suitable for placing in difficult conditions and in sections with congested reinforcement. Use of SCC can also help minimize hearing-related damages on the worksite that are induced by vibration of concrete. Another advantage of SCC is that the time required to place the concrete in large sections is considerably reduced. In this paper the performance of SCC by varying the range of micro silica as partial replacement of cement is studied. When used as an admixture micro silica can improve the property of concrete in both fresh and hardened state .The trial mixes are formed based on the EFNARC specifications. Cement is replaced with various percentage of micro silica (5%, 10%). The workability properties of mix are evaluated by workability tests such as slump flow test, V-funnel. L-Box tests. In this study the performance of concrete mix with micro silica, super plasticizer and VMA is evaluated. It was found that te compressive strength of cubes at 5% replacement is 28% higher than that of 10% replacement.
