BIRSS RSM-1 M350 — two-component polymer-cement R3 repair system
BIRSS RSM-1 M350 is supplied as a kit of 40 kg dry mix and 1 kg liquid component, which together give a rapid-hardening polymer-cement mortar of class R3 to GOST R 56378. It is used to repair vertical, inclined and overhead surfaces under medium loads, including span beams and crossbeams of bridges, and for plastering concrete and stone. Work is carried out at temperatures from −10 to +35 °C, including during periods of transition through 0 °C; at 28 days compressive strength is at least 35 MPa, frost resistance F2 300.
