Early-strength composite cementing material for ventilation flue and preparation method thereof
The invention discloses an early-strength composite cementing material for a ventilation flue and a preparation method thereof. The early-strength composite cementing material for the ventilation flueis prepared from the following components in parts by weight: 15 to 31 parts of cement, 50 to 75 parts of fine aggregate, 0.05 to 0.15 part of a water reducing agent, 1.3 to 7 parts of a composite mineral admixture for concrete, 0.12 to 0.5 part of an organic early strength agent, 0.12 to 0.5 part of an inorganic early strength agent, 1 to 3 parts of an accelerator and 0.02 to 0.08 part of an antifoaming agent. The preparation method of the early-strength composite cementing material for the ventilation flue comprises a step of stirring the raw materials for 2-10 minutes until the raw materials are uniformly mixed to obtain a finished product. When in use, water is added into the finished cementing material, and stirring is conducted for 2-10 minutes to obtain slurry, wherein the water adding amount is 12.5-14.5% of the mass of the finished cementing material. The method is suitable for both production operation on a factory production line and nomadic production, and has the advantages of simplicity and convenience in production operation; and the finished cementing material has the advantages of fast development of early strength, short demoulding time, strong quality stability,low comprehensive cost, difficulty in deformation and good water resistance.
本发明公开了一种通风烟道用早强复合胶结料及其制备方法，一种通风烟道用早强复合胶结料包括重量比例为15～31份的水泥、50～75份的细骨料、0.05～0.15份的减水剂、1.3～7份的混凝土用复合矿物掺合料、0.12～0.5份的有机早强剂、0.12～0.5份的无机早强剂、1～3份的速凝剂以及0.02～0.08份的消泡剂，一种通风烟道用早强复合胶结料的制备方法包括将原料搅拌2～10min至混合均匀后得到成品，使用时将成品加水搅拌2～10min得到浆料，加水量为成品质量的12.5～14.5％，即适合于工厂化生产线上生产作业，也适用于游牧式生产，具有生产操作简便，产品早期强度发展快，脱模时间短，质量稳定强，综合成本低，不易变形和耐水性好的优点。
