Pakol Inektsionny B (rapid-hardening microcement) — crack injection down to −15 °C
This finely dispersed high-flow mix with particles no larger than 0.05 mm (average size 5–10 µm) is intended for injection filling of through and internal cracks, caverns and separations in concrete, stone and brick structures and for restoring their monolithic integrity. The rapid-hardening microcement is used in tunnels and metro, on columns and beams, and can be injected down to −15 °C without heating. At a water/solids ratio of 0.4 the grout reaches 60.0 MPa in compression after 28 days (B45), watertightness W16, frost resistance F1 800.
