AI Technical Summary

Problems solved by technology

A large number of these impurities lead to titanium gypsum replacing natural gypsum as a retarder or adding raw materials to cement, which will cause a large drop in the strength of cement.
The most commonly used method is to use titanium gypsum as a filling material for roadbed materials. Although a part of titanium gypsum can be used, the amount is limited, which cannot solve the current situation of a large amount of titanium gypsum accumulation, and titanium gypsum is used as a solid waste resource. , such a simple filling process will cause a waste of resources, which does not meet the current goal of high-value solid waste treatment

Description

technical field [0001] The invention belongs to the field of solid waste resource treatment, and in particular relates to a preparation method of titanium gypsum-based autoclaved aerated concrete. Background technique [0002] With the rapid development of the economy and the continuous advancement of urbanization, in order to better build cities, people's demand for materials is increasing, and natural materials are consumed in large quantities. With the improvement of environmental protection awareness, more and more people call for reducing the use of natural materials, increasing research on industrial waste, and using certain means to replace natural materials with these wastes in construction projects. [0003] Titanium dioxide is a material with a wide range of applications, and it is in great demand in industries such as coatings, cosmetics, and papermaking. Titanium gypsum is a by-product of titanium dioxide produced by the sulfuric acid process. In order to neut...
