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 is 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 concrete applications, MasterFinish 790 can be used to keep the air content of fresh concrete below the industry-accepted limit of 3 per cent.

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
