Dry-mixed mortar and preparation method thereof
The invention discloses dry-mixed mortar. The dry-mixed mortar comprises the following raw materials in parts by weight: 40-60 parts of cement, 20-50 parts of artificial sand, 40-70 parts of building aggregate, 10-15 parts of first modified iron tailing powder, 8-15 parts of second modified iron tailing powder, 1-5 parts of water glass, 3-5 parts of a water reducing agent and 6-8 parts of a water retaining agent. The invention also discloses a preparation method of the dry-mixed mortar. According to the dry-mixed mortar and the preparation method thereof provided by the invention, the artificial sand and the modified iron tailing powder are used for replacing natural sand, and the building aggregate is combined, so that resources are saved, and the prepared finished product is higher in strength, better in water-retaining property and lower in preparation cost through a proper proportion.
本发明公开了一种干混砂浆。所述干混砂浆包括以下重量份的原料：水泥40~60份、人工砂20~50份、建筑骨料40~70份、第一改性铁尾矿粉10~15份、第二改性铁尾矿粉8~15份、水玻璃1~5份、减水剂3~5份、保水剂6~8份。本发明还公开了一种干混砂浆的制备方法。本发明提供一种干混砂浆及其制备方法，利用人工砂及改性铁尾矿粉来代替天然砂，结合采用建筑骨料，节约了资源，且通过合适的比例使得制得的成品强度更高，保水性更好，制作成本更低。
