PREPARATION FOR USE
Pour the required quantity of the dry mix in the mixing bowl or mixer.
Add water 12-14% of the mix weight. (3-3.5 litres per 25 kg package)
Stir mechanically or manually until the mix is completely wet.
Use the prepared mix within 2 hours after adding water.
Compressive strength class of hardened concrete C30/37 EVS-EN 206
Hardened Concrete C40 has increased waterproofness and watertightness.
Can also be processed with mixing pumps.
25 kg of dry concrete makes approx. 12 litres of ready mix. (0.012 m3)
Concrete hardening in temperature conditions of +200 C will develop the following approximate strength values:
48 hours over 20 MPa
7 days over 30 MPa
28 days over 37 MPa
NB! Lower temperatures slow down the hardening speed of concrete. To be used in below-freezing temperatures down to -100 C the manufacturer produces dry concrete with an anti-freezing additive. The bag is marked respectively.
RECOMMENDATIONS – WARNINGS
Substrate and ambient temperature during the application process must exceed zero. Avoid freezing of the freshly poured concrete.
Recommended layer thickness at levelling work is not less than 20 mm.
Drying fresh surfaces must be protected from rain and direct sunlight. If necessary use water to moisten freshly poured concrete.
This product contains cement. Contact with water will cause an alkaline reaction. Can cause skin irritation. In the event of contact with eyes, rinse immediately with plenty of water. For more detailed information please refer to the Safety Data Sheet.
Bagged mix powder has to be stored in dry conditions.
The shelf life of the mixture powder is up to 1 year.
