Properties of self consolidating concrete for prestressed members
In Western Europe the idea was picked up at the end of the last century.
The main drive to develop self-compacting concrete’s was the option to improve the labor conditions at the building site and in the factory (noise, dust, vibrations).
Shrinkage of SCC was of magnitude entirely comparable with that of NVC.
This can result in improved structural capacity and/or serviceability compared to conventionally reinforced concrete in many situations.
Prestressed concrete is used in a wide range of building and civil structures where its improved performance can allow longer spans, reduced structural thicknesses, and material savings compared to simple reinforced concrete.
In this study the area has been covered is making the design mix of self-compacted concrete and it’s performance – economic comparisons with prevailing conventional grade of concrete of M-40 grade.
Self-compacting concrete (SCC) was first developed in Japan, in the early nineties of the previous century, under the stimulating leadership of Prof. The main idea behind self-compacting concrete was, that such a concrete is robust and relatively insensitive to bad workmanship.
