Early Strength
CBA®
A new concept in grinding aids, CBA additive offers all the benefits of traditional grinding aids such as increased grinding efficiency and cement flowability. In addition, in many cases it has been found to improve the strength, particularly the late strength, of cement. A "Grinding Aid Plus," CBA allows the cement producer to trade off strength gains for reduced fineness and achieve lower unit power savings compared with other grinding aids. It has also been known to improve the workability of cement mortars and concrete.

ESE®
The ESE series of additives are available to enhance the early strength of cement. Unlike other early strength enhancers, ESE cement additives provide their performance benefit without the use of chloride or thiocyanate ions.

HEA2®
HEA2 is an effective dispersant for use as a grinding aid/pack set inhibitor for portland cement and other hydraulic cements. It improves the efficiency of the grinding process by preventing the newly fractured cement particles from reagglomerating. HEA2 increases mill output at the same cement fineness, reduces grinding costs, increases cement strengths and increases cement flowability. It is effective in both open circuit and closed circuit cement mills.

MTDA®
A chemical additive which acts as an effective grinding aid/pack set inhibitor on portland or blended cements. It increases mill output at the same cement fineness, reduces grinding costs, improves cement strengths, increases cement flowability and is easy and safe to handle.

TDA®
Aqueous compositions which combine the performance of traditional grinding aids with set acceleration, water reduction and/or strength enhancement to provide optimum performance to meet the specific needs of the producer. TDA additives can increase both the grinding efficiency and the all age compressive strengths of the cement, reduce cost of cement production and increase the rate of hydration. In addition, they increase the workability of cements, mortars and concretes and increase the flowability of cement during handling, storage or packaging, resulting in lower handling costs and reduced waste.

Tytron®
Developed at Grace laboratories, Tytron represents a new chemistry for use in the production of cement for masonry applications. Interground during the cement manufacturing process, Tytron allows cement manufacturers to achieve performance consistent with requirements of ASTM C 91-95c Standard Specification for Masonry Cement. In addition, it provides important performance benefits such as excellent workability, long board life, superior water retention or water repellency.

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.
