Masonry Design: Adding super-plasticizers to concrete

May 08, 2011  Plasticizers (often called super-plasticizers) are chemical admixtures which cut the electrostatic attraction in cement . This allows the cement to become more evenly dispersed in the concrete mix, and creates a stronger concrete as a result. Another significant benefit to using a super-plasticizer is the increased workability of the concrete.
