Is it necessary to use sulphate resisting cement in alkaline areas?
Acid resisting cement is a kind of powdery material made of high acid resistant material and hardening agent, which are mixed or mixed separately according to proper proportion.
1. acid can be applied in chemical industry, petroleum, metallurgy, machinery, textile, papermaking, sugar and other industrial equipment in construction engineering, the floor in the equipment foundation, acid corrosion and acid storage tank, chimney lining workshop, building waste and gaseous acid corrosion, can be prepared by acid resistant clay masonry brick acid and board; can be mixed with acid and coarse aggregate (gravel), fine aggregate (sand) acid and preparation of acid resistant concrete.2. can not be used by hydrofluoric acid, fluosilicate, 300 degrees above phosphoric acid and advanced fatty acids and oleic acid, palmitic acid, and alkaline salt erosion engineering. When used in the food industry, sodium fluoride in sodium fluosilicate should be tested to prove that it is not harmful to humans.
The sulfate resisting silica cement is divided into two categories: medium sulfate resistant Portland cement and high sulfate resistant Portland cement. A suitable cementitious material with resistance to moderate concentration of sulfate ion is prepared by adding proper amount of gypsum in the proper proportion of Portland cement clinker, which is called medium sulfate resisting portland cement. Middle sulfur resistant cement. Code P & MSR. A cementitious material with high resistance to sulfate ion corrosion is prepared by adding proper amount of gypsum into the clinker of proper proportion of Portland cement clinker, which is called high sulfate silica cement. High sulfur resistant cement.
