Mapeplast R815

Water-Reducing and Set-Retarding Admixture

Mapeplast R815 is a multi-usage admixture that when used at a low dosage, provides water-reduction with no impact on set-time. However, at higher dosages, while providing additional water reduction, it also delays set, and as such, Mapeplast R815 conforms to ASTM C494 Type A, B and D and CSA A23.1. Mapeplast R815 increases strength and improves workability and finishing characteristics.

Reduced mix water requirement needed to produce a given slump or consistency (reduced water-cementitious ratio)
Improved workability
Increased compressive and flexural strength
Reduced cracking and shrinkage
Reduced permeability and increased water tightness
Increased freeze-thaw resistance
Superior surface appearance
