Performance of Self Compacting Concrete Containing Fly Ash and MIRHA: Optimum Mix Design and Structural Behavior

Properties of hardened concrete are very important for load resistance, durability, stability and aesthetic point of view; its properties in fresh state are also very vital for good workmanship. In view of this, the self compacting concrete simply called SCC was initiated. The aim of producing of...
