Get PriceSynthetic calcium sulfate dihydrate, obtained from sulfuric acid waste of chemical plants and waste of the fine fraction of limestone, is a potential source of gypsumcontaining raw materials. We investigated the processing of synthetic calcium sulfate dihydrate from sulfuric acid waste to gypsum, highstrength gypsum binder, and anhydrite.
Get PriceThe calcination of limestone is one of the oldest technical processes and it is still of actual interest. Very early calcitic mortars from Turkey have been investigated and compared with materials of other early civilisations with Egyptian mortars containing gypsum as well as medieval dolomitebased mortars from alpine regions.

Get PriceAug 21, 2019· For instance, limestone often breaks down because of carbonation. The sulfuric acid in acid precipitation reacts with the limestone. This replaces the rock with a new chemical product, called calcium bicarbonate Ca(HCO 3) 2. Oxidation also causes chemical weathering. Oxygen in the air reacts with chemicals in different landforms.
Get PriceThis book introduces the chemistry of aromatics with a brief discussion of the aromatic character and a survey of historical aspects, particularly the development of the organic dye industry during the 19th century.
