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. WebThis video explains the concept of steam curing of concrete at high pressure.
