Pakol Remontny BK — rapid-hardening thixotropic mortar for work at −10…+7 °C

Thixotropic repair mortars

Rapid strength gain and placing at temperatures from −10 to +7 °C distinguish this coarse-grained thixotropic mortar for the autumn and spring period: 12.0 MPa after 2 h, 15.0 MPa in compression after 4 h. It is used for urgent structural repair of spalls, gouges and cavities on vertical, inclined and overhead surfaces of bridges, tunnels, dams, tanks, columns and beams. After 28 days: 60.0 MPa (B45), W16, F1 600, class R4; workability retention 15 min.
