Abstract:A new family of comb polymers has been developed that have been found to overcome many performance shortcomings typically exhibited by conventional high range water reducing agents, commonly referred to as superplasticizers. This paper discusses some theoretical considerations associated with comb polymer type super-plasticizers, and reports on several key performance advantages such as extended slump life without prolonged set time, minimal variation in slump and air performance as a function of cement brand, and linear dosage response in mortar flow tests.
