Abstract
An improved liquid membrane-forming curing composition and a method of curing fresh concrete. The curing composition is effective for providing a membrane layer over the exposed surfaces of fresh concrete for retaining the water of hydration therein for the proper curing of the concrete. In a preferred embodiment, the curing composition comprises a vegetable oil, preferably a non-refined vegetable oil such as coconut oil, corn oil, cottonseed oil, palm oil, rapeseed (canola) oil, soya oil, sunflower oil, and mixtures thereof; a surfactant effective for providing a stable oil-in-water emulsion, a drying agent, and water.
Claims20
A method of curing fresh concrete comprising the steps of:
- preparing a pre-emulsion concentrate comprising a vegetable oil, a drying agent, and a surfactant to form a pre-emulsion concentrate;
- mixing the pre-emulsion concentrate with water to form a curing composition;
- and
- applying the curing composition to the exposed surfaces of the fresh concrete;
- wherein said curing composition comprises about 5.0 to about 95 percent water, about 5.0 to 60.0 percent vegetable oil, about 1.0 to about 20.0 percent of surfactant, and about 0.1 to about 5.0 percent of a drying agent.
