Method for preparing calcium sulphosilicate-dicalcium silicate-calcium sulphoaluminate system from calcium carbide slag calcium raw material and improving later strength of cement
The invention discloses a method for preparing a calcium sulphosilicate-dicalcium silicate-calcium sulphoaluminate system by using calcium carbide slag as a calcium raw material and improving the later strength of cement, belonging to the technical field of building materials. According to the invention, different industrial waste residues are calcined at a high temperature to prepare the system with calcium sulphosilicate serving as a main mineral and dicalcium silicate and anhydrous calcium sulphoaluminate serving as auxiliary materials and main mineral components in sulphoaluminate cement, so the system has good adaptability to sulphoaluminate cement; and when the system is added into sulphoaluminate cement or a silicate-sulphoaluminate cement system, post-stage compression resistance and breaking strength can be improved to a certain extent, expansion performance can be improved, the post-stage strength growth rate can be improved, the problem of insufficient post-stage strength storage force can be solved, and the advantages of sufficient raw material selection, low cost, economy, environmental protection and the like can be provided.
电石渣钙质原料制备电石渣钙质原料制备硫硅酸钙‑硅酸二钙‑硫铝酸钙体系及提升水泥后期强度的方法属于建筑材料技术领域，利用不同的工业废渣在高温下煅烧制备出以硫硅酸钙为主要矿物，硅酸二钙和无水硫铝酸钙为辅的体系，且硅酸二钙和硫铝酸钙同时也是硫铝酸盐水泥中的主要矿物成分，因此本体系与硫铝酸盐水泥具有良好的适应性，将其添加到硫铝酸盐水泥或者硅酸盐‑硫铝酸盐水泥体系中，不仅能够在一定程度上提高其后期的抗压抗折强度，改善膨胀性能，提高后期强度增长率，解决了后期强度蓄力不足的问题，而且在原料的选择上，具有原料充足、成本低廉、经济环保等优势。
