Abstract

Self-Compacting Concrete (SCC) is a new type of concrete that can be spread in  heavily congested regions under its own weight. and without vibration. It has excellent deformability  and high resistance to segregation and bleeding. see is a result of the technological advancement in  the area of concrete admixtures. This paper presents an attempt to produce SCC from the available  materials in Egypt and investigates the workability requirements and tests of SCC. The experimental  program consists of casting and testing eighteen SCC-mixes. Silt different parameters are considered  as; cement content, type of fine materials, content of limestone powder, dosage of viscosity- enhancing&  admixtures, dosage of air-entraining admixtures, and dosage of superplasticizers. The test results  indicated that viscosity-enhancing admixture together with the new generation superplasticizers based  on a modified polycarboxylic-polyether are the keystone for producing Sec. Three main tests which differentiate SCC from ordinary)· concrete were carried out and  explained in this paper. These tests are  slump-flow test,  V-funnel test, and filling-capacity tests. SCC-mixes provided stump flow up to 850 mm, filling capacity up to 100%,passing time up to 7 sec., and compressive strength up to 36 3 MPa,  These results are quite appropriate for using SCC in any construction site. It is believed that SCC is a  promising construction material in the near future.
