Abstract
The invention relates to an acid/alkali-corrosion-resistant cement, belonging to the field of architecture. The acid/alkali-corrosion-resistant cement comprises 40-50% of clinker, 3-10% of raw gypsum, 15% of scum, 15% of coal powder, 15% of iron ore slag, 5% of SiO2 powder, 5% of corrosion-resistant organic substance and 5% of anti-expansion component. The technique comprises the following steps: pulverizing the clinker, raw gypsum, corrosion-resistant organic substance, SiO2 powder and scum, and calcining at 700-800 DEG C to obtain the finished product. The acid/alkali-corrosion-resistant cement has the advantages of simple technique, low cost and no environment pollution in the production process.
