Green ecological environment-friendly cement and preparation method thereof
The invention relates to green ecological environment-friendly cement, and the cement is prepared from 30 to 40 parts of modified superfine alkaline slag powder, 10 to 15 parts of calcite powder, 15 to 20 parts of kieselguhr, 3 to 5 parts of wollastonite powder, 5 to 7 parts of alkali activator and 5 to 9 parts of water, wherein the modified superfine alkaline slag powder is obtained by crushing industrial alkaline slag by superfine crushing equipment and then carrying out surface treatment by a coupling agent. The modified superfine alkaline slag powder is added into the cement formula, so the compactness and compressive strength of the cement are improved; the wollastonite powder is added, so the whole cement material also has the advantages of low shrinkage and high ductility. Compared with the traditional cement, the green ecological environment-friendly cement disclosed by the invention also has the remarkable advantages of high anti-permeability grade, strong weather resistance, no corrosion to reinforcing steel bars and the like.
本发明涉及一种绿色生态环保水泥，包括改性超细碱性矿渣粉末30‑40份、方解石粉10‑15份、硅藻土15‑20份、硅灰石粉3‑5份、碱激发剂5‑7份以及水5‑9份；其中，所述改性超细碱性矿渣粉末为工业碱性矿渣经超细微粉碎设备粉碎后，由偶联剂进行表面处理得到。本发明通过在水泥配方中添加改性超细碱性矿渣粉末，提高水泥的密实度和抗压强度；通过添加硅灰石粉，使得水泥材料整体还具有低收缩性、高延性的优点。本发明所述的绿色生态环保水泥与传统水泥相比，还具有抗渗等级高、耐候性强、不腐蚀钢筋等显著优点。
