Abstract
Dry compound from clay, quartz sand, starch as binding addition agent is prepared, 20% of water solution of sodium hydroxide is added to it, the obtained mixture is formed and exposed to bake for 1.5 hour under 960-1050 deg. C., at that, the ratio of quartz sand and clay is 2.33:1, and the ratio of dry compound and solution of sodium hydroxide is 6.25:1. Thus, the method is simplified, the obtained bricks have low heat transfer and low gravity, but are solid, cold, heat and chemical-resistant.
