Alccofine and steel in self-compacting concrete

Abstract

Self-compacting concrete (SCC) is considered as a concrete which can be placed and compacted under its
self weight with little or no vibration effort and which is at the same time cohesive enough to be handled without
segregation or bleeding. It is used to facilitate and ensure proper filling and good structural performance of restricted
areas and heavily reinforced structural members. SCC was developed in Japan in the late 1980s to be mainly used for
highly congested reinforced structures in seismic regions. Recently, this concrete has gained wide use in many countries
for different applications and structural configurations. SCC can also provide a better working environment by
eliminating the vibration noise. There are many advantages of using SCC, especially when the material cost is
minimized. These include:
1.Reducing the construction time and labor cost;
2.Eliminating the need for vibration;
3.Reducing the noise pollution;
4.Improving the filling capacity of highly congested structural members.
5.Facilitating constructability and ensuring good structural performance.
