BIRSS RBM M400 — fibre-reinforced R3 mix for airfield and road pavements
Airfield and road pavements with intensive dynamic loads, as well as structures under impact, are repaired with BIRSS RBM M400. It contains special cements, graded sand, fibre and chemical admixtures; the mortar does not segregate, hardens quickly and has compensated shrinkage. Use of the mix as a pourable mortar and at temperatures below +5 °C is not recommended. Class R3; compressive strength 20, 30 and 40 MPa at 3, 7 and 28 days, flexural at 28 days 7 MPa, W16, F2 400.
