Application Technology and Economic Analysis of Low Carbon Cement Prepared by Titanium Gypsum

To deal with global climate change, people have to strike a balance between "cement" and "CO₂ reduction". A new method was proposed to produce super sulfate cement (SSC) by pressing and filtering the titanium gypsum raw material with 50% water content in Panxi Area, and fully mixed it with other solid wastes such as titanium extraction tailings, steel slag, furnace slag and fly ash. This gelling properties of Fe and Millpebs ball mill technology were used to combine with other wastes innovatively. The low-carbon preparation process with "One Mill" process and hydration mechanism of SSC were clarified by physical and mechanical analysis, and the CO₂ emission reduction effect was also calculated. The goals of heighten the ratio of titanium gypsum (content > 10%) in the SSC and reduction the cost were not only achieved, the performance of SSC were in line with national standard (32.5). It will make a contribution to realize the carbon peak and carbon neutralization.
