Low-carbon cement mortar and preparation method thereof
The invention relates to low-carbon cement mortar and a preparation method thereof, and the low-carbon cement mortar is prepared from the following raw materials in parts by weight: 350 to 550 parts of low-carbon cement, 1300 to 1400 parts of tin tailing sand and 220 to 230 parts of water. Wherein the low-carbon cement utilizes construction waste regenerated micro powder and silicon-manganese slag powder. According to the low-carbon cement disclosed by the invention, by utilizing the synergistic effect of the construction waste regenerated micro-powder and the silicon-manganese slag powder, the defects that the construction waste regenerated micro-powder is irregular in particle, loose, porous and poor in activity are overcome, the effect of increasing the strength of cement mortar is obvious, and the comprehensive utilization rate of the construction waste is also improved. And the low-carbon cement mortar further utilizes the tin tailing sand as fine aggregate, so that the recycling treatment of the tin tailings is facilitated. Compared with the prior art, the invention has the characteristics of simple process, low cost, carbon emission reduction by more than 30%, high strength and good durability.
本发明涉及一种低碳水泥砂浆及其制备方法，所述低碳水泥砂浆按照重量份数计，包括以下原料：低碳水泥350‑550份、锡尾矿砂1300‑1400份、水220‑230份。其中低碳水泥利用了建筑垃圾再生微粉和硅锰渣粉。本发明中低碳水泥利用建筑垃圾再生微粉和硅锰渣粉的协同作用，克服了建筑垃圾再生微粉颗粒不规则、疏松多孔、活性差的缺点，不仅对水泥砂浆强度的增加作用明显，还提高了建筑垃圾综合利用率。而低碳水泥砂浆则进一步利用了锡尾矿砂作为细骨料，有利于锡尾矿的资源化处置。与现有技术相比，本发明具有工艺简单、成本低廉、降低30％以上的碳排放、强度高、耐久性好的特点。
