TYTRON® Cement Admixture Data Sheet

A revolutionary new technology for Masonry Cement

Product Description 

TYTRON® is a proprietary technology developed at the research laboratories of GCP. It represents a revolutionary new chemistry for use in the production of cement for masonry applications. 

Designed to be interground during the cement manufacturing process, TYTRON® use allows cement manufacturers to achieve performance consistent with the requirements of ASTM C 91-95c Standard Specification for Masonry Cement. In addition, its use provides important performance benefits such as excellent workability, long board life, water repellency and superior water retention. TYTRON® is supplied in a stable solution so that storage and use in a variety of different conditions and climates is never a problem.

For special cases where extra performance is desired by the masonry manufacturer or user, the basic TYTRON® formulation can be modified to produce enhanced performance in the areas of workability, board life, water retention and/or strength. These additional benefits can essentially be added through “custom-designing” by GCP technical personnel to produce the TYTRON® S, TYTRON® A, TYTRON® R, TYTRON® P or TYTRON® W variants. Combinations of benefits may also be obtained through the use of such products as TYTRON® WA, TYTRON® SA, etc. as desired by the customer. Such custom formulations would typically require laboratory work by GCP, utilizing the customer’s raw materials, followed by a plant trial for formula optimization, with the ultimate goal being a product that is uniquely suited for the specific raw materials and performance requirements of the market.
