Abstract: A device and method for reinforcing recycled aggregate based on in-situ C—S—H production including a first, second, third chamber, and a blast drier. A spray structure arranged on the top of the third chamber; the first and second chamber connected to the spray structure through pumps. A hollowed container arranged at the bottom of the spray structure. A certain gap reserved between the bottom of the container and the bottom of the third chamber, the bottom of the third chamber is provided with at least one drain outlet; the blast drier connected to the bottom of the third chamber, and a cover is arranged on the top of the third chamber. The first chamber contains calcium hydroxide solution. The second chamber contains a mixed solution of TEOS, water and anhydrous ethanol. The container is arranged in the third chamber, and the container is used to contain to-be-treated recycled aggregate.

Abstract: A carbonized brick of recycled concrete powders and a preparation method thereof are provided, belonging to the field of concrete materials. The preparation method includes: adding composition A to a liquid storage tank; introducing composition B into the liquid storage tank to react with a solid waste solution to generate calcium bicarbonate solution; filling recycled powders into a molding die, decomposing the calcium bicarbonate solution by heat, reacting generated carbon dioxide with calcium ions leached from a C—S—H gel in the recycled powders to produce calcium carbonate, and precipitating, crystallizing and cementing in the molding die together with calcium carbonate produced by decomposing calcium bicarbonate solution, and resulting in strength of the recycled powders.
