Retardation

Hydrophobe®
A series of multipurpose additives interground during the manufacture of prepared masonry cement to entrain air, impart water repellency, control setting time, extend board life and improve workability. It eliminates the need to add separate materials to impart this combination of properties to masonry cements.

RDA®
Aqueous formulation intended for intergrinding during cement production which retards the setting time of portland or blended cements.


TytroniX®
Developed at Grace laboratories, TytroniX utilizes a new chemistry that results in a dramatic improvement in the performance of low air mortar cements. Interground during the cement manufacturing process, the use of TytroniX allows cement manufacturers to achieve the high flexural bond strength and low air levels consistent with the requirements of ASTM C 1329-96 Standard Specification for Mortar Cement. At the same time it imparts excellent workability to mortar cements and provides superior boardlife and water retention to the mortar.
