WHAT IS SEGREGATION OF CONCRETE AND

05-04-2014  Concrete is a mixture of aggregate, cement, water admixture. The sizes and their specific gravities are different from each other. For example the specific gravity of most of the aggregates fall in the range between 2.6 to 2.7 and that of most of the cement is in between 3.1 to 3.2. Because of this they show a tendency to separate from each other.
