GLIMS® PRO CRF-40 Rapid — rapid-hardening flowable R4 mortar for urgent repair
Rapid-hardening flowable R4 mortar for fast-track repair of bridges, tunnels and industrial floors, including at −10 °C; 10 MPa after 2 hours.

For local structural repair of concrete and reinforced concrete with strength not lower than B20, GLIMS® PRO CRT-40 is suitable: a thixotropic mortar of class R3 to GOST R 56378-2015. It is placed without formwork on vertical, inclined, horizontal and overhead surfaces of bridges, bridge spans, tunnels, car parks, viaducts and equipment foundations, as well as port and hydraulic structures, chimneys and cooling towers. Compressive strength is 15 MPa after one day and 40 MPa after 28 days, adhesion from 1.5 MPa, W12, F2 300.
