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.
