Colored low-calcium carbon sequestration cementing material and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to a colored low-calcium carbon sequestration cementing material and a preparation method thereof. The preparation method comprises the following steps: grinding a calcium raw material, a siliceous raw material and a mineral coloring agent in a ball mill to obtain a uniformly mixed raw material; mixing the raw material with water, pressing into a green body, sintering and cooling to obtain the colored low-calcium carbon sequestration cementing material, wherein the molar ratio of calcium to silicon of the calcium raw material to the siliceous raw material is 1.0-1.9; the sintering temperature ranges from 1150 DEG C to 1400 DEG C. The color of the colored low-calcium carbon-sequestration cementing material prepared by the preparation method is stable and not easy to change or fall off under the action of high temperature, and the colored low-calcium carbon-sequestration cementing material has very important practical significance for expanding the application scene of the low-calcium carbon-sequestration cementing material. In addition, it is accidentally found that part of coloring ions can enter calcium silicate ore phase crystal lattices, the activation effect on the calcium silicate ore phase is achieved, and the reaction activity of the calcium silicate ore phase can be improved.
本发明属于建筑材料技术领域，具体涉及一种彩色低钙固碳胶凝材料及其制备方法。该制备方法包括如下步骤：将钙质原料、硅质原料和矿物着色剂在球磨机中粉磨，得到混合均匀的生料；将所述生料与水混合，压制成坯体，烧结，冷却，得到彩色低钙固碳胶凝材料；其中，所述钙质原料、硅质原料的的钙硅摩尔比为1.0‑1.9；所述烧结的温度为1150‑1400℃。利用该制备方法制得的彩色低钙固碳胶凝材料，其颜色经过高温作用稳定不易改变或脱落，对拓展低钙固碳胶凝材料的应用场景具有非常重要的实际意义。此外，本发明意外发现，部分着色离子可以进入硅酸钙矿相晶格，对硅酸钙矿相有活化作用，可以提高其反应活性。
