Characteristics
As a universal and economical product, XJ-1022 is recommended for production of flowing mortars with normal and special cementitious binder system due to the following characteristics
l Super water reducing effect for cement based material applications
l Low dosage compared to traditional water reducing agent
l High dispersion, fluidity and workability
l Improvement of early and final strength of cement based system
Key Properties
- Good dispersability
- High water reduction
- Excellent adaptability with kinds of cement
- High flowability in mortar or concrete
Dosage and Handling
XJ-1022 should be dry-blended with the other dry ingredients at a minimal dosage of 0.1% ~ 0.3% by total weight of cementitious components. The actual dosage should be determined through suitable tests prior to production and application
