摘要

Process for the manufacture of silicon-calcareous bricks based on quartz sand, lime and water, essentially characterized by the fact that such materials have to be subjected to internal reactions that produce the formation of hydrosilicates, which being molded at high pressures are finally cooked and hardened by steam pressures in autoclaves for a period of five to eight hours.
