Abstract
Mag-oxy cements are made by either molding or heat treating after molding at elevated temperatures. The products are made utilizing colloidal silica and/or phosphates and the products are made by either molding or by heat treating after molding at elevated temperatures. The products treated at 250.degree. F. show considerably less solubility particularly where both phosphates and silicates are present in which case the weight loss based on the reactables may be as low as approximately 2 percent. When heat treated at 300.degree. F., there is no weight loss in practically all cases; but a pickup in weight occurs indicating an additional hydration. Sheet molding compounds are also made by processes which provide a deficiency of water of hydration.
