Magnesia slag stone powder normal-temperature carbon sequestration artificial aggregate and preparation method thereof
The invention belongs to the technical field of concrete, and particularly relates to a magnesium slag stone powder normal-temperature carbon sequestration artificial aggregate and a preparation method thereof. The preparation method of the magnesium slag and stone powder normal-temperature carbon sequestration artificial aggregate comprises the following steps: (1) adding water into magnesium slag and stone powder, and uniformly stirring to obtain a mixture; (2) pouring the mixture into a disc granulator, starting the disc granulator, and spraying water to prepare an aggregate blank; (3) pre-curing the aggregate green body to reduce the water content of the aggregate green body; and (4) carrying out carbonization reaction on the aggregate green body treated in the step (3) and CO2 gas to obtain the magnesium slag stone powder normal-temperature carbon sequestration artificial aggregate. The magnesium slag stone powder normal-temperature carbon sequestration artificial aggregate disclosed by the invention meets various performance requirements on high-strength aggregate in the standard GB-T-17431.1-2010, and can be used as a raw material of concrete instead of natural aggregate such as sand, stone and the like.
本发明属于混凝土技术领域，具体涉及一种镁渣石粉常温固碳人造骨料及其制备方法。本发明的镁渣石粉常温固碳人造骨料的制备方法，包括下述步骤：(1)向镁渣和石粉中加水搅拌均匀，得到混合料；(2)将所述混合料倒入圆盘造粒机内，启动所述圆盘造粒机，喷洒水，制备得到骨料坯体；(3)对所述骨料坯体进行预养护，降低所述骨料坯体的含水率；(4)使经步骤(3)处理所得的骨料坯体与CO2气体发生碳化反应，即得所述镁渣石粉常温固碳人造骨料。本发明的镁渣石粉常温固碳人造骨料符合标准GB‑T‑17431.1‑2010中对高强度骨料的各种性能要求，能够替代天然骨料如砂、石等作为混凝土的原料使用。
