Low-alkali high-strength cement clinker and processing technology thereof
The invention relates to the technical field of building materials, and particularly discloses a low-alkali high-strength cement clinker and a processing technology thereof. The low-alkali high-strength cement clinker is prepared from the following components in percentage by weight based on the total weight of raw materials: 80 to 85 percent of limestone, 2 to 5 percent of fly ash, 2 to 4 percent of copper slag, 2 to 4 percent of phosphorus slag, 2 to 3 percent of montmorillonite and 4 to 7 percent of silica. The processing technology of the low-alkali high-strength cement clinker sequentially comprises the following steps: grinding raw materials, homogenizing, calcining and cooling; and the calcining temperature is 1300 to 1350 DEG C. The alkali content of the produced cement clinker is lower than 0.5, the 3d compressive strength of the cement clinker can reach 28.7-36.9 Mpa, the 28d compressive strength of the cement clinker can reach 56.9-66.4 Mpa, the effects of reducing the alkali content and improving the strength are achieved, and higher construction requirements can be met.
本申请涉及建筑材料的技术领域，具体公开了一种低碱高强水泥熟料及其加工工艺。一种低碱高强水泥熟料，以原料的总重量计，其包括以下重量百分比的组分：石灰石80‑85%、粉煤灰2‑5%、铜渣2‑4%、磷渣2‑4%、蒙脱石2‑3%、硅石4‑7%；低碱高强水泥熟料的加工工艺依次包括：生料研磨、均化、煅烧、冷却；=煅烧温度为1300‑1350℃。本申请生产的水泥熟料的碱含量低于0.5，且水泥熟料的3d抗压强度可以达到28.7‑36.9Mpa，28d抗压强度可以达到56.9‑66.4Mpa，达到了在降低碱含量的同时提高强度的效果，可以满足更高的施工要求。
