A method for making a carbonated precast concrete product includes: obtaining a mixture including at least one binder material, an aggregate, and water; molding the mixture into a molded intermediate; demolding the molded intermediate to obtain a demolded intermediate, the demolded intermediate having a first water-to-binder ratio; conditioning the demolded intermediate to provide a conditioned article having a second water-to-binder ratio less than the first water-to-binder ratio of the demolded intermediate; moisturizing at least one surface of the conditioned article with an aqueous medium, thereby causing a weight gain of the conditioned article and providing a moisturized product, a first portion of the moisturized product having a third water-to-binder ratio greater than a fourth water-to-binder ratio of a remainder of the moisturized product; and curing the moisturized product with carbon dioxide to obtain the carbonated precast concrete product.

A composite blast furnace mineral powder and a synthetic material made from same. The composite blast furnace mineral powder consists of the following materials in percentage by mass: 40-98.4% of blast furnace mineral powder, 7-20% of acrylic polymer emulsion or 1.5-3% of redispersible latex powder, 0.1-2% of fiber, 0-3% of pigment and the balance of filler. The composite blast furnace mineral powder can be pressed into a profile or a brick blank.

Provided herein are manufacturing processes that include (1) subjecting precursor-containing solids to dissolution under acoustic perturbation to yield an initial slurry including dissolved precursors; (2) subjecting the initial slurry to hydrothermal synthesis to yield a subsequent slurry including siliceous solids formed from the dissolved precursors; and (3) subjecting the subsequent slurry to cementation to yield a cemented siliceous solid. Also provided herein are cemented siliceous solids formed by the manufacturing processes.
