Abstract
Setting and hardening accelerating agent for siliceous hydraulic binders wherein: a) it is obtained by hydration, in the usual pressure and temperature conditions, and grinding of a siliceous hydraulic binder aqueous suspension; b) the suspension particles are sufficiently fine for the agent to meet the following test requirements: an aqueous suspension in a sedimentation specimen at 20.degree. C., containing 10 grams (dry weight) of the accelerating agent in 100 ml of water, must have a sedimentation deposit height at least equal to 50% of the initial height at the end of two days; c) it is in the form of an aqueous suspension.
