Concrete is a most widely used construction material in the world. As the use of
concrete becomes more widespread the specifications of concrete like durability, quality, compactness and optimization of concrete becomes more important. Self-compacting concrete (S.C.C) is a very fluid concrete and a homogenous mixture that solves most of the problems related to ordinary concrete. Besides, S.C.C gets compacted under its own weight and there is no need for an internal vibrator for the body of the mold. This specification helps the execution of construction components under high compression of reinforcement.
Unlike other papers about S.C.C, which want to introduce this concrete and different
test methods of it, this paper investigates the durability and strength of this concrete and studies the role of all important factors in durability of S.C.C by doing some examinations.
Another part of this paper studies the obstacles in improvement of S.C.C and tries to offer some solutions as follows:
a) Using lightweight aggregates in production of S.C.C in order to decrease the
risk of segregation and specific weight of this concrete.
b) Study of production of S.C.C in ready-mixed concrete factories
c) Study of using suitable and economic fillers in production of S.C.C considering the
resources and talents of each country
The last part of this paper introduces some important projects executed with S.C.C in
U.S.A, France and Japan and gives a brief information about these projects and will
provide the readers with reasons that why S.C.C is used in these projects.
