Effect of Mineral Admixture on Fresh and Hardened Properties of Self Compacting Concrete

Prof. Shriram H. Mahure, Dr. V. M. Mohitkar

Self-compacting concrete (SCC) is one of the High Performance Concrète with excellent strength and durability properties. However, its mix proportioning and testing methods for flow characteristics are different from those of the ordinary concrete. SCC has high powder content and a super plasticizer for enabling flow while keeping coarse aggregate in a viscous suspension. The powder is usually cement and a filler material. In this paper an attempt has been made to study fresh and hardened properties of self compacting concrete using cement klin dust (CKD) as partial replacement of cement in different percentages in addition to filler.Modified Nan-su method has been used for design mix as the study was carried out for medium strength of concrete.
