Low-carbon cement clinker and preparation method thereof
The invention discloses a low-carbon cement clinker, which is mainly composed of the following mineral components: 40 to 60 wt% of C7MS4, 30 to 50 wt% of beta-C2S, and 2 to 5 wt% of a chemical component MgO. According to the invention, high-content C7MS4 is introduced into low-carbon cement clinker minerals for the first time, so that the defects that the carbonization rate of beta-C2S is too high, and carbonization inside and outside a product is not uniform are effectively improved; the activity of C7MS4 is improved by modulating the content of MgO, and the carbon sequestration effect can be effectively guaranteed; particularly, high carbonization strength can be achieved under the industrial tail gas carbonization conditions of low CO2 concentration and low air pressure, the required carbonization time is short, and good carbonization condition adaptability is achieved; the preparation method is simple, convenient to operate and suitable for popularization and application.
本发明公开了一种低碳水泥熟料，其矿物组成主要为C7MS4和β‑C2S，其中C7MS4的含量为40‑60wt％，β‑C2S的含量为30‑50wt％，化学成分MgO的含量为2‑5wt％。本发明首次提出在低碳水泥熟料矿物中引入含量高的C7MS4，有效改善β‑C2S碳化速率过快、制品内外碳化不均匀等缺陷；并通过调制MgO的含量改善C7MS4的活性，可有效保证固碳效果；尤其可在CO2浓度低、气压低的工业尾气碳化条件下达到高碳化强度，所需的碳化时间少，具有良好的碳化条件适应性；且涉及的制备方法较简单、操作方便，适合推广应用。
