How Super Are Superplasticizers?| Concrete Construction Magazine

May 01, 1982 · HOW THEY ARE USED. Superplasticizers can be used in three ways: to create flowing, self-leveling concrete without increasing water, without reducing cement and without sacrificing strength; to produce workable, high-strength concrete by reducing the water and thus the water-cement ratio; or, to save cement by reducing both the water and cement contents while maintaining the same water-cement ratio and the same workability.

Superplasticizer - an overview | ScienceDirect Topics

Superplasticizers can lead to increased air content when the mortar or concrete is mixed. This air may improve the workability to some extent but air contents of more than 3% for a non air-entrained concrete reduce durability and must be avoided.
