BIRSS 59 S1 M800 Moroz — high-strength flowable R4 mix for the cold season
BIRSS 59 S1 M800 Moroz provides high strength at sub-zero temperatures: when hardening at −15 °C the mortar reaches 45 MPa in compression in 28 days, at +20 °C 80 MPa. The mix is placed at temperatures from −15 to +5 °C to repair road and airfield pavements, bridges, parking areas, industrial floors and equipment foundations. Initial set no earlier than 45 minutes, final set no later than 80 minutes; modulus of elasticity 30,000 MPa, water impermeability W 20, class R4.
