Cement clinker doped with strontium slag and preparation method thereof
The invention discloses cement clinker doped with strontium slag and a preparation method of the cement clinker, and belongs to the technical field of cement materials. The cement clinker doped with the strontium slag is prepared from the following raw materials in percentage by mass: 70-80% of limestone, 16-25% of construction waste, 1-2% of sulfate slag and 1-3% of an auxiliary agent, the auxiliary agent comprises dolomite and the strontium slag in a mass ratio of 1: (1-3), the particle size of the auxiliary agent is 40-400 microns, the proportion of the auxiliary agent with the particle size of 150-400 microns is 50-60 wt%, and the proportion of the auxiliary agent with the particle size of 40-80 microns is 30-40 wt%. The preparation method comprises the following steps: step 1, weighing the raw materials in proportion, mixing and grinding to obtain a cement raw material; 2, calcining the cement raw material until clinker minerals are completely formed; the raw materials are easy to obtain, the production cost is low, the method is simple, and recycling of resources is effectively achieved. The cement clinker provided by the invention not only has good burnability, but also has good mechanical properties, and also has unexpected good corrosion resistance.
本发明公开了一种掺入锶渣的水泥熟料及其制备方法，属于水泥材料技术领域。本发明提供的一种掺入锶渣的水泥熟料，由包括以下质量百分比的原料制成：石灰石70～80％，建筑垃圾16～25％，硫酸渣1～2％，助剂1～3％，所述助剂包括质量比1：1～3的白云石和锶渣，所述助剂的粒度为40‑400μm,其中，粒度为150～400μm的助剂占比为50～60wt％，粒度为40～80μm的占比为30～40wt％。本发明的制备方法包括：步骤1.按比例称取各原料，混合、研磨，得到水泥生料；步骤2.将水泥生料煅烧，直至熟料矿物完全形成。本发明原料来源易得，生产成本低，方法简单，有效地实现了资源的回收利用。本发明的水泥熟料不仅具有良好的易烧性能，并且力学性能好，同时具有预料不到的良好抗腐蚀性能。
