Shah Rushabh Hemant (Roll No. 852) discusses curing of concrete. Curing involves maintaining moisture content and temperature to allow for proper hydration of cement. Methods include ponding, fog spraying, and steam curing. The objectives are to reduce shrinkage and maintain strength, impermeability, and durability. Curing should continue for at least 7 days, and up to 21 days in cold weather. Proper curing results in higher quality concrete.
