Bulk solid waste-based geopolymer thermal insulation concrete and preparation method thereof
The invention provides a bulk solid waste-based geopolymer thermal insulation concrete. The concrete is prepared from, by mass, 100 parts of recycled coarse aggregate, 10-45 parts of fly ash, 10-45 parts of mineral slag powder, 2-10 parts of sodium hydroxide, 10-20 parts of sodium silicate, 0-130 parts of sands, 0-30 parts of floating beads, 10-15 parts of vitrified micro-bubbles, 0-6 parts of silica fume, 0.5-0.8 part of a water reducing agent and 15-25 parts of water, wherein the sands are prepared from, by mass, 0-50 parts of natural sands, 0-35 parts of reclaimed sands and 0-45 parts of iron tailing sands. The invention also provides a preparation method of the bulk solid waste-based geopolymer thermal insulation concrete. The preparation method improves the cost performance of the thermal insulation concrete, effectively improves the cyclic utilization rate of resources, and has great economic benefits.
本发明提供一种大宗固废基地聚物保温混凝土，由以下质量份的原料组成：再生粗集料100份，粉煤灰10～45份，矿渣粉10～45份，氢氧化钠2～10份，硅酸钠10～20份，砂子0～130份，漂珠0～30份，玻化微珠10～15份，硅灰0～6份，减水剂0.5～0.8份，水15～25份；其中，按质量份计，所述砂子由天然砂0～50份、再生砂0～35份和铁尾矿砂0～45份组成。本发明还提供了上述大宗固废基地聚物保温混凝土的制备方法。本发明提供的制备方法提高了保温混凝土的性价比，有效提高了资源的循环利用率，具有较大的经济效益。
