- Especially optimized for processing from 2 chamber silos or mobile screed processing units
- Suitable for floor heating systems
Properties:
- Minimal shrinkage/expansion under dry resp. wet curing conditions minimizing the risk of micro-cracking
- Excellent flowable workability
- Variable water addition
- Ready for covering with ceramic tiles after 3 days, for moisture sensitive floor coverings after approx. 14 days
- 90 min. working time and 12 MPa (1740 psi) compressive strength after 24 hours
- Final strength of more than 30 MPa (4350 psi) after 28 days with suitable sand quality and 32 % water addition
- Very good adhesion to properly prepared concrete
- Excellent water resistance, no strength loss under water
- High tensile strength allowing thin applications on de-coupled screed applications
