Euclid Chemical has announced the release of EUCON AWA-P20, its new anti-washout concrete admixture.

EUCON AWA-P20 is a ready-to-use liquid admixture designed to modify the rheology of self-consolidating concrete and prevent the loss of cement and fine aggregate during the placement of underwater concrete, while not discoloring the concrete. Featuring thixotropic properties, it can also be used to reduce excessive bleeding and segregation of concrete or mortar during pumping.

Recommended for use with the PLASTOL line of polycarboxylate-based admixtures, EUCON AWA-P20 does not contain any added chlorides or chemicals known to promote the corrosion of steel. It also minimizes environmental impact by reducing concrete washout and eliminating the need for expensive de-watering during underwater construction.

The applications for EUCON AWA-P20 include: 

• Self-consolidating concrete
• Underwater bridge and dam repair
• Underwater grouting and mortar applications
• Damming underground rivers and lakes in mining operations
• Anti-segregation aid for use with lightweight and heavyweight aggregates
• Concrete designs using gap-graded aggregates

EUCON AWA-P20 meets the ASTM C494 Type S standard specification for chemical admixtures for concrete applications, as well as the requirements of the CRD-C661-06 specification for anti-washout admixtures for concrete from the U.S. Army Corps of Engineers.
