Pumping high-temperature-resistant concrete for blast furnace foundation and preparation method of pumping high-temperature-resistant concrete
The invention discloses pumping high-temperature-resistant concrete for a blast furnace foundation and a preparation method thereof.The pumping high-temperature-resistant concrete for the blast furnace foundation is prepared from, by weight, 40-60 parts of clay waste bricks, high-aluminum waste bricks and calcined alumina coarse aggregate and 15-25 parts of clay waste bricks, high-aluminum waste bricks and calcined alumina fine aggregate. The invention relates to a high-strength concrete, which is prepared from the following raw materials in parts by weight: 2 to 7 parts of clay waste bricks, high-aluminum waste bricks and calcined alumina fine powder, 3 to 8 parts of silicon dioxide micro powder, 18 to 22 parts of Portland cement, 0.1 to 0.3 part of micro powder dispersing agent, 0.2 to 0.5 part of polycarboxylic acid high-efficiency water reducing agent, 0.01 to 0.06 part of anti-water-seepage agent hydroxy propyl cellulose and 11 to 12 parts of water. The pumpable high-temperature-resistant concrete prepared by the invention can maintain a liquid flowing state for 3-4 hours without condensation in a stirring state, the pumping construction performance is good, a blast furnace foundation after casting molding and curing can resist high temperature of 700 DEG C, and the effective service time is 15-20 years.
本发明公开了一种高炉基础用泵送耐高温混凝土及其制备方法，所述高炉基础用泵送耐高温混凝土，包括下述重量份的原料：粘土废砖、高铝废砖、煅烧矾土粗骨料：40‑60份，粘土废砖、高铝废砖、煅烧矾土细骨料：15‑25份，粘土废砖、高铝废砖、煅烧矾土细粉料：2‑7份，二氧化硅微粉：3‑8份，硅酸盐水泥：18‑22份，微粉分散剂：0.1‑0.3份，聚羧酸高效减水剂：0.2‑0.5份，防沁水剂羟丙基纤维素：0.01‑0.06份，水：11‑12份；本发明制备的可泵送耐高温混凝土，在搅拌状态下可维持3‑4小时的液态流动状态不凝结，泵送施工性能好，浇注成型、养护结束以后的高炉基础可耐高温达700℃，有效使用时间为15‑20年。
