Self-compacting mortar and preparation method thereof
The invention belongs to the field of building materials, and particularly relates to self-compacting mortar and a preparation method thereof. The self-compacting mortar provided by the invention comprises the following components in parts by weight: 120-300 parts of Portland cement; 20-120 parts of sulphoaluminate cement; 50-90 parts of fly ash; 100-300 parts of molybdenum tailing powder; 20-80 parts of limestone powder; 5-30 parts of an expanding agent; 200-400 parts of molybdenum tailing ceramsite; 1-10 parts of fibers; 1-5 parts of a water reducing agent; and 100-200 parts of water. According to the mortar provided by the invention, the molybdenum tailing powder and the molybdenum tailing ceramsite are used as production raw materials, so that resource utilization of molybdenum tailings is realized; the construction time of the mortar can be adjusted within 20min-1h, the initial setting time is 2-4h, the 28d strength reaches C30-C50, and the volume weight is within 2000kg/m < 3 >; in addition, the mortar does not need to be vibrated manually in the whole casting process, and construction is convenient.
本发明属于建筑材料领域，尤其涉及一种自密实砂浆及其制备方法。本发明提供的自密实砂浆以重量份数计，其组分包括：硅酸盐水泥120～300份；硫铝酸盐水泥20～120份；粉煤灰50～90份；钼尾矿粉100～300份；石灰石粉20～80份；膨胀剂5～30份；钼尾矿陶粒200～400份；纤维1～10份；减水剂1～5份；水100～200份。本发明提供的砂浆以钼尾矿粉和钼尾矿陶粒作为生产原料，实现了钼尾矿的资源化利用；该砂浆的施工时间可在20分钟～1小时内进行调整，初凝时间为2～4小时，28d强度达到C30～C50，容重在2000kg/m3以内；而且，该砂浆在浇铸过程中全程无需人工振捣，施工方便。
