Abstract
Polysuccinimide and/or polyaspartate, copolymers of succinimide and aspartate and the polymers cross-linked with a diamine are demonstrated to be enhancement agents for the preparation of cementitious materials. The agents may be added to the dry cementitious mixture or the water which is added to form the cementitious material upon hardening. The enhancement agents improve the workability of the wet cementitious mixture, reduce slump loss during mixing, transport, and placement of the wet cementious mixture; and may provide extra strength upon hardening of the cementitious material.
