Effect of Fibers Addition and nano colloidal on Mechanical Properties of SCC Composite

Self compacting concrete, SCC is a relatively new type of concrete that can flow through densely reinforced concrete structural elements under its own weight without need for vibration. It offers very attractive technical benefits when combined with fibers and can create a type of composite material. This paper reports a laboratory investigation on the contribution of nano particles, the polypropylene and two new steel fibers on mechanical properties of SCC composite. The fibers were used as resin in SCC as matrix and the mechanical properties of composite materials such as compressive strength, modules of elasticity and modules of rapture were surveyed. It was concluded that addition of nano colloidal and fibers can improve some of the mechanical properties of self compacting concrete.
