Silica-aluminum cementing material shrinkage reducing agent as well as preparation method and application thereof
The invention belongs to the technical field of building materials, and particularly relates to a silicon-aluminum cementing material shrinkage reducing agent and a preparation method and application thereof.The silicon-aluminum cementing material shrinkage reducing agent is prepared from, by weight, 1-11 parts of quick lime and/or pretreated carbide slag and 1-8 parts of pretreated gypsum and/or gypsum, 0.5 to 7 parts of sulphoaluminate cement clinker and/or aluminate cement; the preparation method comprises the following steps: taking the raw materials in parts by weight, mixing and grinding to obtain powder; and the method can be applied to the treatment of silicon-aluminum low-carbon cementing materials. The shrinkage reducing agent can effectively reduce the shrinkage rate of a cementing material, is good in stability and wide in application range, and can bring huge benefits to economy and environment.
本发明属于建筑材料技术领域，具体涉及一种硅铝质胶凝材料减缩剂及其制备方法和应用，该硅铝质胶凝材料减缩剂按照重量份数计，包括如下原料：生石灰和/或预处理电石渣1～11份，预处理石膏和/或石膏1～8份，硫铝酸盐水泥熟料和/或铝酸盐水泥0.5～7份；制备方法包括如下步骤：按照重量份数取用原料，混合，研磨，得到粉体；能够应用于处理硅铝质低碳胶凝材料。该减缩剂可以有效降低胶凝材料的收缩率，稳定性好，适用范围广，可对经济和环境带来巨大的效益。
