Web3.Steam Curing: This type of curing is done for precast concrete products manufactured in the factory. Due to steam, the material is heated evenly and the strength is obtained at a very rapid rate. Even in short intervals of stacked precast products, steam can penetrate and cure pieces of all sides. WebIn the precast concrete industry, steam curing allows increased production by a more rapid turnover of molds and formwork. Maximum temperatures range from 104°to 212°F (40° to 100°C), with the optimum being in the 150°to 175°F (65°to 80°C) range. The higher the initial temperature of the curing environment, the lower the ultimate strength.
