TYTRONIX® Cement Admixture Data Sheet

A revolutionary new technology for Mortar Cement

Product Description 

TYTRONIX® is a proprietary product developed at the research laboratories of GCP. It utilizes a revolutionary new chemistry that results in a dramatic improvement in the performance of low air mortar cements. 

Designed to be interground during the cement manufacturing process, TYTRONIX® use allows cement manufacturers to achieve the high flexural bond strength and low air levels consistent with the requirements of the ASTM C 1329-96 Standard Specification for Mortar Cement. In addition, TYTRONIX® imparts superior workability to mortar cements, such that, in blind trowel tests performed by professional masons, low air mortars made with TYTRONIX® outranked the standard high air masonry cements. TYTRONIX® is also formulated to provide superior board life and water retention to the mortar.

For cases where manufacturers or masons have special performance needs, the base TytroniX® formula can be modified to provide enhanced benefits. These variants of TYTRONIX®, known as TYTRONIX® SA, TYTRONIX® A and TYTRONIX® AR can be formulated to provide superior water retention, strength or set time control as needed by the customer.
