TECHNICAL SPECIFICATIONS
Compressive strength class of hardened concrete: C25/30 EVS-EN 206:2014
25 kg of dry concrete makes approx. 12 litres of the ready mix. (0.012 m3)
Concrete hardening in temperature conditions of +20 0C shall develop the following approximate strength values:
 48 hours 15 MPa
7 days  21 MPa
14 days  28 MPa
28 days over  30 MPa
NB! Lower temperatures slow down hardening speed of concrete.
 
RECOMMENDATIONS – WARNINGS
Substrate and ambient temperature during the application process shall exceed zero. Avoid freezing of the freshly poured concrete.
Recommend layer thickness at levelling works is 10-50 mm
Drying fresh surfaces shall be protected from rain and direct sunlight exposure. If necessary use water to moisten freshly poured concrete.
The product contains cement. Contact with water causes alkaline reaction. Can cause skin irritation. Upon contact with eyes rinse immediately with plenty of fresh water. For more specific information please refer to the Safety Data Sheet.
 
STORAGE
Bagged mix powder has to be stored in dry conditions.
Shelf life is 1 year.
