ABSTRACT:
This invention relates generally to the field of cement, especially cement for underwater application. The invention provides a composition for preparing cement that solidifies underwater comprising exothermic micro particles and base cement. Exothermic micro particles are less than about two thousand two hundred and fifty micrometers in diameter and can be, for example, calcium chloride. The invention further provides a kit for preparing cement that solidifies underwater comprising exothermic micro particles in a container and base cement. The invention provides a method of underwater construction or repair comprising mixing a composition comprising exothermic micro particles and base cement with water and applying the composition to an underwater structure where the composition solidifies. The composition, kit and method are particularly well suited for swimming pool repair.
