Abstract
An agent for accelerating hardening of cement for use in an underground mining installation employing concrete-like packs including run-of-mine coal. The agent comprises by weight one and a half parts triethanolamine, five parts sodium carbonate and one part potassium carbonate. Too rapid setting of quick setting cement is avoided by the agent because a slurry of cement in water is mixed with a slurry of agent and run-of-mine coal in bentonite in a mixer immediately before being added to a pack so that setting cement does not occur in pipes leading to the mixer.
