Calcium-magnesium synergistic carbonized high-strength cementing material and preparation method thereof
The invention discloses a calcium-magnesium synergistic carbonized high-strength cementing material and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing part of calcined dolomite with water and an optional additive, and standing to obtain a mixture; performing compression molding on the mixture to obtain a blank body; and performing CO2 curing on the green body to obtain the calcium-magnesium synergetic carbonized high-strength cementing material. According to the method, a large amount of low-grade dolomite is subjected to resource treatment based on an in-situ carbonization reaction mechanism by utilizing a calcium-magnesium synergistic carbonization regulation technical method, so that a new technical route is provided for resource utilization of the low-grade dolomite, and a high-added-value utilization route of the dolomite can be effectively widened; the technological process is green and low-carbon, and the method can be widely applied to a carbon dioxide capture/collection technology and preparation of novel low-carbon cementing materials and concrete.
本发明公开一种钙镁协同碳化高强胶凝材料及其制备方法。该制备方法，包括如下步骤：将部分煅烧白云石与水和可选的外加剂混合均匀并静置，得到拌合物；将拌合物压制成型，得到胚体；将坯体进行CO2养护，得到钙镁协同碳化高强胶凝材料。本发明利用调控钙镁协同碳化技术方法，基于原位碳化反应机理，将大量低品位白云石进行资源化处置，为其资源化利用提供新技术路线，可有效拓宽白云石高附加值利用路径；本发明工艺流程绿色低碳，可广泛应用于二氧化碳捕获/收集技术以及新型低碳胶凝材料和混凝土中的制备。
