Curing concrete with steam
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. WebApr 20, 2024 · 9 Methods Of Curing Of Concrete. 2. Ponding.
