Abstract 

Self-compacting concrete is state-of-the-art technology in all over the world in construction field. This concrete which has high performance can be used for casting heavily reinforced sections, places where there can be no access to vibrators for compaction and in complex shapes of formwork which may otherwise be impossible to cast, giving a far superior surface than conventional concrete. In another aspect, using types of fibers can redeem mechanical and dynamical characteristic of concrete as well as reducing cracking in concrete. In this study, we are going to scrutinize both combined and entity effect of polypropylene and glass on mechanical properties of concrete and Rheological Characterization of Self- Compacting Concrete. For this case, we prepared 10 specimen including (A) polypropylene fiber with Volume fraction of  0.1, 0.2, 0.3 and Glass with volume friction of 0.1, 0.2, 0.3 and (B) combined polypropylene fiber and glass. Inspection of these experiments has shown that combined polypropylene fiber and glass can enhance tensile and bending strength, plus it dramatically increase toughness of concrete.
