In current years, self-compacting concrete (SCC) has gained comprehensive use for placement in congested
reinforced concrete structures with difficult casting conditions. Self-compacting concrete (SCC) consists one of the
very modern developments in concrete technology. With its excellent deformability, high fluidity, and better durability
potential, it marks a milestone in the construction industry. It also offers a rapid rate of concrete placement, with faster
construction pace and ease of flow around congested reinforcement. Use of SCC can also support reduce hearingrelated damages on the worksite that are induced by vibration of concrete. In this present investigation the performance
of SCC by varying the range of micro silica as partial replacement of cement is studied. The experimental mixes are
formed based on the EFNARC specifications. Cement is replaced with various percentage of micro silica (5%, 6%, 7%,
8%, and 9%). The workability properties of combination are evaluated by workability tests such as slump flow test, Vfunnel, L-Box tests. In this learning the performance of concrete mix with micro silica, super plasticizer evaluated. This
project focuses on the effects of micro silica on all the main properties of self-compacting concrete in the fresh and
hardened state.
