APPLICATION OF SELF CONSOLIDATING CONCRETE IN CONSTRUCTION INDUSTRY

Self consolidating concrete (SCC) is a novel concrete which uses in many structures in all over on the world. It is a concrete which flows under own weight and completely fills the mold, passes from congested reinforcement without any bleeding or segregation. This type of concrete contains high range water reducing admixture and often viscosity modifying admixture also more fine aggregate compared to conventional concrete. It can reduce labor requirement, increase strength, durability and productivity, eliminate noise and hazard. For these good specifications, SCC uses in improper reach concreting, dense reinforcement elements, thin layer concrete construction and so on. Mahab Ghodss consultant engineering applied SCC in some Dams and tunneling projects. This article presented some executive experience of three projects which some structure of them constructed by SCC successfully. Finally some recommendation for mix design and whole scale construction SCC in site are proposed.
