Title: Compressive Strength Of Metakaolin Based Self-Compacting Concrete
Abstract: Self-compacting concrete (SCC) refers to high strength concrete which will compact under its own weight and does not require external vibration. SCC composition consists of maximum volume of fine aggregate and powder content, whereas coarse aggregate occupies lesser quantity. The concrete prepared for SCC was highly fluid and it was achieved by Super plasticizers and Stabilizers of optimum dosages. In present work, an experimental study was made to study the strength of SCC using metakaolin (MK). Here cement was replaced by MK with 15%. For an experimental investigation, conventional vibrated concrete CVC and SCC cube and cylinder specimens were cast and tested at the age of 28 days after curing. The concrete mix design was developed using ACI code provisions for conventional and SCC type concrete. With the obtained results, it was found that compressive and split tensile strength of SCC specimens found to be higher compared to CVC. Finally, the increase of powder content by mineral admixtures improves the flow property and strength parameters of SCC.
