Abstract
PURPOSE:To obtain the titled high-quality product in a short time by curing, while heating, a mixture comprising cement, water. foam and aggregate in a pressure-specified chamber. CONSTITUTION:The objective product can be obtained by curing, while heating, a mixture comprising cement and water as the chief materials and foam and/or aggregate in a chamber where the ambient air pressure is so controlled as to be equal to the inner pressure of said foam and/or the open cell in said aggregate. According to this process, said mixture will be cured without causing any expandable deformation. Therefore, the foam-contg. slurried mixture poured into a mold can be transferred immediately into the curing chamber without waiting for the setting at normal temperature, the obtaining the objective high- strength concrete product with uniform porous texture.
