MasterFinish 790

Air-detraining admixture for concrete

How does MasterFinish 790 work?

MasterFinish 790 air-detraining admixture is a patented liquid admixture formulated for use in concrete. MasterFinish 790 facilitates a reduction in entrapped and, where applicable, entrained air content during mixing.

MasterFinish 790 meets ASTM C 494/C 494M requirements for Type S, Specific Performance, admixtures.

Recommended uses:

Concrete where a reduction in air content is desired
Heavyweight concrete
Interior flatwork concrete

Air quality verification testing required for use in air-entrained concrete.

What makes MasterFinish 790 a unique solution?

MasterFinish 790 is formulated to reduce the total air content of concrete, as desired. In non air-entrained con-crete applications, MasterFinish 790 can be used to keep the air content of the fresh concrete below the industry-accepted limit of 3 percent.

What are the benefits of MasterFinish 790?

Reduces the air content of concrete mixtures
Ready-to-use in the proper concentration for rapid, accurate dispensing
Uses standard admixture dispensing equipment
Helps to maintain design strengths of concrete mixtures
Reduces the need to over-design concrete mixtures to offset the effects of higher-than-desired air contents
Permits the use of normal dosages of air-entraining admixtures to achieve desired air contents
Reduces rejected load potential
Reduces the effect of higher-than-desired air contents on concrete bleeding
Helps to improve the integrity of interior flatwork concrete
