Abstract
The invention relates to the technical field of mortars, concretes, and other compositions based on cement, and in particular to agents capable of modifying their rheological characteristics, in particular workability. Workability may be defined as the property of a hydraulic binder to remain workable during as long a time as possible. The invention relates to novel agents of the acrylic copolymer type having urethane functions for improving the workability of hydraulic binders, to a method of preparing such novel agents, to binders containing them, and to uses for them. Such agents have the advantageous property of not retarding the setting time.
