Present-day self-compacting concrete classified as an advanced construction material. Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It can flow under its weight, completely fills the formwork that achieves full compaction, even in the presence of congested reinforcement. The hardened self-compacting concrete is dense, homogeneous and has the same engineering properties and durability as traditional vibrated concrete. A remarkable improvement of health and safety achieved through the elimination of vibrators. A substantial reduction of environmental noise loading on and around a site. The composition of SCC mixes includes significant proportions of mineral admixtures, which are currently waste products with no practical applications.
This study aims to make use of the maximum percentage of fly ash in addition to cement and vary the percentage of fine aggregate in terms of total aggregate and understand the properties of fresh and hardened concrete. The workability of SCC increased as the percentage of fine aggregate is increased. The study also intended to find the optimum mix design ratio for the M20 grade that satisfies both the fresh and hardened properties. Slump flow, V-funnel, L-flow and compressive strength tests were carried out to examine the performance of SCC.
