The present disclosure provides a system for COstorage and utilization of a concrete mixing plant and a method thereof. The system includes a slurry making module, a cyclic grinding module and a material storage and application module. The cyclic grinding module can grind, in the presence of a gas containing COand medium balls, a composite slurry prepared by the slurry making module, and can cyclically use the gas containing CO, so as to realize continuous production of a carbon-mineralized slurry. The material storage and application module includes a material storage bin and a mixing machine connected with each other, and the material storage bin is configured to receive and store the carbon-mineralized slurry from a slurry bin. The mixing machine is configured to mix and prepare the carbon-mineralized slurry into a commodity concrete.

System for COstorage and utilization of concrete mixing plant and method thereof

The present invention discloses a method of preparing an alkali activation material by using red mud-based wet grinding and carbon sequestration and an application thereof. The preparation method includes: (1) adding water, red mud, a crystalline control agent, and a grinding aid into a wet grinding carbon sequestration apparatus to perform wet grinding, and simultaneously introducing COuntil a slurry pH reaches 7 to 7.5; and removing wet grinding balls by a sieve to obtain a slurry A; (2) adding carbide slag, water and a water reducer to a wet planetary ball grinder tank for wet grinding, and removing wet grinding balls by a sieve to obtain a slurry B; (3) taking 50 to 80 parts of the slurry A and 20 to 50 parts of the slurry B and mixing them to obtain an alkali activation material.
