WHAT IS SEGREGATION OF CONCRETE AND WHY IT

2014-4-5  In concrete technology, segregation can be of two types. Firstly the coarse aggregate may separate from the main mass of concrete in its plastic state. Secondly, the grout (cement+paste) may separate from the mix. The second one is generally occurs if a concrete is too wet. Theory Behind Segregation

DYNAMIC SEGREGATION OF SELF-CONSOLIDATING

2015-10-15  Segregation is categorized as static or dynamic segregations. Cement paste and coarse aggregate tend to separate vertically when the concrete is at rest before setting, this is so-called static segregation. This separation also occurs horizontally in the presence of flow, which refers to dynamic segregation.

The Effect of Aggregate Properties on Concrete

2000-3-30  Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.
