Research status of carbonation solid waste materials in process industry Available to Purchase

The excessive emission of carbon dioxide (CO₂) is one of the causes of global warming. Countries around the world are actively exploring the most cost-effective carbon dioxide capture and utilization technologies. The purpose of this paper is to summarize the current status of carbon dioxide emissions in process industry (taking the four major process industries in China as an example), and to explore the latest research on the integration of carbonation technology with solid waste in different production fields. In the process industry, carbon dioxide emission reduction strategies mainly include changing the energy supply structure and using new low-carbon production technologies. In the field of carbonation technology, this paper reviews research on preparing nano-CaCO₃- and active silica gel-reinforced cementitious material systems via carbon dioxide mineralization, and on investigating the mechanical properties of directly reinforced materials using CaCO₃ shell and skeleton. In addition, the reaction characteristics of all kinds of carbon dioxide mineralized products and the influence of reaction process conditions on the mineralization process were discussed in detail. Through the carbon dioxide mineralization reaction, the solid waste in the process industry can be secondary treated to improve its utilization value. The development prospect of carbon dioxide mineralization technology driving all solid waste building materials was prospected.
