Quick-hardening Portland cement and preparation method thereof
The invention discloses quick-hardening Portland cement which is prepared from the following raw materials in parts by weight: 50-60 parts of Portland cement clinker, 35-40 parts of limestone, 0.03-0.06 part of an activating agent and 20-30 parts of waste residues, wherein the activating agent is formed by compounding 2,5-dihydroxyethylpiperazine with one or more of triethanolamine, diethanolisopropanolamine, monoethanolisopropanolamine, tetrahydroxyethyl ethylenediamine and triisopropanolamine; and the waste residues comprise one or more of waste concrete, chippings, tailings and barren rocks. The quick-hardening Portland cement has the advantages of being low in cost and environmentally friendly, waste concrete, chippings, tailings and barren rock are used as raw materials, the cost is low, a new way is provided for recycling of industrial waste residues, and the advantage of quick hardening is achieved.
本发明公开了一种快硬型硅酸盐水泥,由以下重量份原料组成:50‑60份硅酸盐水泥熟料、35‑40份石灰石、0.03‑0.06份活化剂、20‑30份废渣;其中,活化剂由2,5‑二羟乙基哌嗪可与三乙醇胺、二乙醇单异丙醇胺、单乙醇二异丙醇胺、四羟基乙基乙二胺、三异丙醇胺中一种或多种复配而成;废渣包括废弃混凝土、碎屑、尾矿、废石一种或多种;本发明具有成本低廉,绿色环保的优点,利用废弃混凝土、碎屑、尾矿、废石为原料,不仅成本低廉,而且为工业废渣的再利用提供了新的途径,且具有快硬的优点。
