Abstract
Process for the manufacture of thermohydraulically set stones, made of cement and/or lime, quartz powder and coarse-grained filling material, characterized in that cement and/or lime (calculated on the basis of calcium hydroxide) are intimately mixed with powder quartz to approximately in molar proportion and with addition of at most 65 percent by volume of filler and an amount of water which with the cement is in a weight ratio of 0.2 to 0.35 approximately, with the calcium hydroxide in the proportion of 0.4 to 0.6 approximately, the mass is then molded and the air content in the molded body reduced by mechanical treatment, such as tamping, percussion, pressing, possibly under vacuum, unless of 2 percent in volume.
