   Young concrete is protected against desiccation (evaporation of unreacted water). Traditional methods for preventing desiccation involve covering the product with wet burlap or use of plastic sheeting.. For larger projects, such as highways, the surface is sprayed with a solution of curing compound that leaves a water-impermeable coating. [7]
