Self-Compacting Concrete (SCC) is a flowing concrete mixture that, even in the presence of crowded reinforcement, can consolidate and entirely fill up formwork under its own weight without vibrating while it is being poured.SCC was initially described by Japanese researchers in the late 1980s.The main aim of this dissertation is to discuss the effects of various admixtures on the properties of self-compacting concrete. An experimental analysis on self-compacting concrete (SCC) with a water cement content of 0.42 was conducted in this study. Various types of mixes were used, the first included different percentages of silica fumes (SF) mixed with concrete. The second mix includes super plasticizer SP-430 for a notable variation in its strength. Various batches of concrete mix were also used for testing by combining super plasticizer with different chemical admixtures. Since self-compacting concrete is the subject of the research, slump cone and V-funnel tests are performed on fresh SCC, and the compressive strengths, split tensile strengths and flexural strengths of the concrete are measured on hardened blocks as properties. For 7 and 28 days cured specimens, it was discovered that adding 10% silica fumes and 1% SP-430 and various combinations of chemical admixtures with SP-430 respectively to the concrete were found to give noticeable compressive, flexural and split tensile strength also good workability characteristics.
