Description
Curing is the maintaining of a satisfactory moisture content and temperature in concrete during its early stages so that desited properties may develop. Basic principles of curing are stated; commonly accepted methods procedures, and materials are described . Requirements 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 stated Curing requirementsfor precast products, shotcrete, preplaced-aggregate concrete, refractory concrete, plaster, and other applications are given.
