Gypsum And Sulfuric Acid In The Manufacture Of White Cement

PROCESS FOR THE MANUFACTURE OF CEMENT CLINKER

What we claim is 1. A process for the manufacture of cement clinker of low fluorine content from phosphoric acid byproduct gypsum according to the gypsum-sulphuric acid process which comprises heating the byproduct gypsum without any additives to a temperature within the range of 500 to 900 C. in the sulphur dioxide-containing waste gasses produced in the calcination furnace of the .

Acid Attack on Concrete Effects amp; Results of Acid Attack

Feb 14 2017 Note that the aggression of the acid attack is not only because of its pH value but also due to the presence of CO 2 in relation with the hardness of water.. Effect of Sulphuric Acid on Concrete Sulphuric acid attack causes extensive formation of gypsum in the regions close to the surfaces and tends to cause disintegration and mechanical stresses which ultimately lead to spalling

manufacture of sulfuric acid and white cement from gypsum

In such calcium sulfate to cement processes gypsum upon decomposition acts as a calcium source for the cement production while the SO 2 produced is used to produce sulfuric acid. With gypsum CaSO 4 .2 2 O the same is dehydrated to CaSO 4 and the anhydrate blended with carbon and sand or shale with the blended mixture fed to a kiln.

Sulfuric Acid Attacks Concrete CivilEnvironmental

Sep 29 2010 Sulphuric acid is very damaging as it combines an acid attack and a sulfate attack. The reaction between sulfuric acid and the calcium compound in concrete will form calcium salts which are soluble in water. These water soluble salts leach away causing a loss of volume and cohesion of the cement

Cement History of cement Britannica

Cement - Cement - History of cement The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2000 years ago and of subsequent construction work in western Europe.
