Abstract

Cement products are made from waste products of the soda industry, namely lime granules residual from the slaking of burnt lime, and comprising calcium carbonate, calcium oxide, and di- and tri-calcium silicates and aluminates, and the solid distillation sludge comprising calcium carbonate and calcium oxide and from which calcium chloride has been removed, by working up these products with a material of high silicic acid content and water, and casting and subsequently steam hardening the mixture. The material of high silicic acid content may be sand and/or quartz powder or meal. Optionally a hydratable silicate material such as Portland cement or basic blast furnace slag is included to increase the compressive and tensile strength. A leavening agent such as 0.035% by weight aluminium paste may also be included to yield porous products. A preferred composition consists of 30% by weight lime granules, 30% distillation sediment, 35% quartz meal, and 5% hydratable silicate, to which 45% of water is added, based on the total solids weigth.
