Curing is defined as the process of maintaining a satisfactory moisture content and a favorable temperature in concrete during hydration of the cementitious materials so that desired properties of the concrete are developed. Two systems of providing the required moisture are explained in detail: (I) main-taining a moist environment by application of water; and (2) prevention of IOSS of mixing water by use of sealing materials. Basic principles of successful curing are outlined, and commonly accepted methods, procedures, and materials are described. Recommendations are given for curing pavements and other slabs on ground; for structures and buildings: and for mass concrete. For each of these categories, methods, materials, time and temperature of curing are recommended. Brief sections comment on curing requirements for precast products, shotcrete, preplaced aggregate concrete, refractory concrete, plaster and other applications.
