Formula and preparation method of energy-saving and consumption-reducing foam concrete material
The invention discloses a formula of an energy-saving and consumption-reducing foam concrete material, which consumes a large amount of two admixtures of coal ash of a thermal power plant and steel slag powder of an iron and steel plant to reduce the use amount of cement in foam concrete, and has the advantages of waste utilization, no toxicity, no harm, energy saving and consumption reduction. Due to the addition of the Huoqianjin, the functions of reducing the water cement ratio of the foam concrete, inhibiting shrinkage cracking and improving the compactness and the early strength are achieved; after the fly ash is mechanically activated, the production quantity of a condensation material capable of filling a hollow microporous structure between pores of the hardened slurry can be increased, the compactness of the hardened slurry is improved, and the compressive strength of the foam concrete is improved; the content of CaO and MgO can be reduced through carbonation pretreatment of the steel slag powder, and the problem of poor stability is solved. The invention further discloses a preparation method of the energy-saving and consumption-reducing foam concrete material.
本发明公开了一种节能降耗的泡沫混凝土材料的配方，该配方中大量消耗热电厂粉煤灰、钢铁厂的钢渣粉两种掺合料，以减少泡沫混凝土中水泥的用量，具有废物利用、无毒无害、节能降耗的优点；华千素的加入具有降低泡沫混凝土的水灰比、抑制收缩开裂、提高致密性和早期强度的功能；粉煤灰在经过机械力活化后，可提高能够填充硬化浆体气孔间壁中空的微孔结构的凝结材料生产量，提高硬化浆料的密实性，提高泡沫混凝土的抗压强度；钢渣粉经过碳酸化处预处理可减少CaO和MgO的含量，解决安定性不良问题。还公开了一种节能降耗的泡沫混凝土材料的制备方法。
