There are two commonly known methods of producing self compacting type concretes, namely, the Powder and Admixture Methods. 

The Powder Method uses superplasticisers in conjunction with very high cementitious material contents (i.e. cement, fly ash, slag, etc) to form a paste which controls the homogeneity of the mix, improves its flowability and holds the mix constituents together and resists segregation.

The Admixture Method is based on the use of the new generation of polycarboxylate superplasticisers which offer the capability of providing for improved flowability, viscosity and cohesion, as well as workability retention. Depending on the characteristics of constituent materials, a viscosity modifier may also be required.
