Abstract
The present invention relates to methods to protect curing cement or concrete from excess evaporative water loss and/or from rain, excess heat loss, or excess heat gain. More particularly the method relates to coating curing cement or concrete with a layer (or layers) of a fibrous mass composed of ground cellulose, water, a viscosity enhancing polymer, a hygroscopic swelling agent and, optionally, additives selected on the basis of the properties desired (e.g., rain resistance, heat absorption from the sun, heat reflectance, or heat insulation). The invention also relates to compositions comprising a layer of cement or concrete and a layer (or layers) of such a fibrous mass.
