Research Progress of Low-Carbon Cementitious Materials
Cementitious material based on synergistic industrial wastes can be used as a new product for low-carbon transformation. It can aid in resource recycling and suitable consumption and utilisation of various industrial wastes. The proposed material can reduce a large amount of CO2 emitted during calcination in cement production and the Sugarcane Bagasse Ash as a Supplementary Cementitious Material. Sugarcane bagasse ash was collected from a sugar production plant in Mahabubnagar, Telangana, India, in an effort to confirm the material properties reported in earlier literature (Ganesan et al. 2007; Chopperla et al. 2019; Murugesan et al. 2020a, b).The Availability and Accessibility of Sugarcane Bagasse Ash for its

Quantification of CO2 emission from the preparation and
The cement industry as a high-emission and an energy-intensive sector, has always been a key concern for the sustainable development. In 2020, China produced over half of the world's cement and the relevant carbon emission is enormous. It's an urgent need to development low-carbon cementitious materials, such as the sulphoaluminate Cement plants normally perform grinding in close circuit configuration, combining a mill with an air classifier that controls the particle size of the output.
