Abstract
A method of rapidly forming in place a cementitious structure comprising mixing a cement composition with an amount of a water soluble citrate effective to accelerate the setting of the cement in the presence of sufficient water for hydraulic setting of the cement, and delivering the resulting composition while fluid to the place for forming the cementitious structure.

The method of rapidly forming in place a cementitious structure comprising mixing a cement composition with an amount of a water-soluble citrate effective to accelerate the set of the cement in the presence of sufficient water for hydraulic setting of the cement, and delivering the resulting composition while fluid to the place for forming the cementitious structure, said amount of water-soluble citrate being at least 4% by weight based on the weight of cement.
A method of accelerating the set of a cement mix comprising the steps of adding an accelerating amount of a water-soluble citrate to a cement mix, and allowing the cement mix to set, said amount of water-soluble citrate being at least 4% by weight based on the weight of the cement.
