Preparation method and application of anti-freezing and load-bearing fly ash foam concrete
The invention discloses a preparation method and application of anti-freezing and load-bearing fly ash foam concrete, and the preparation method of the fly ash foam concrete comprises the following steps: mixing cement, fly ash, quartz powder, quartz sand, polypropylene fiber, a foam stabilizer and manganese dioxide, uniformly stirring to obtain a dry material, uniformly mixing the dry material, a water reducing agent and water to obtain slurry, and carrying out extrusion molding on the slurry to obtain the anti-freezing and load-bearing fly ash foam concrete. The fly ash foam concrete solves the problems that common foam concrete is low in strength and poor in freezing resistance, due to the fact that the change of pore structure parameters of the fly ash foam concrete and the change of pore structure parameters of the common concrete are different under the action of freezing and thawing cycles, the strength of the foam concrete is improved, and the foam concrete has the advantages of being high in strength and good in anti-freezing performance. By means of the method for evaluating the compressive strength of the fly ash foam concrete based on the fly ash mixing amount, the compressive strength of the fly ash foam concrete can be accurately evaluated.
本发明公开了一种集抗冻承重于一体的粉煤灰泡沫混凝土制备方法及应用，粉煤灰泡沫混凝土的制备方法，包括：将水泥、粉煤灰、石英粉、石英砂、聚丙烯纤维、稳泡剂和二氧化锰混合，搅拌至均匀，得到干料，将干料、减水剂和水混合均匀，得到浆料，向浆料中加入发泡剂，搅拌至均匀，静置发泡，养护，得到粉煤灰泡沫混凝土，该粉煤灰泡沫混凝土解决了普通泡沫混凝土存在的强度低、抗冻性差的问题，由于粉煤灰泡沫混凝土和普通的混凝土在冻融循环作用下孔结构参数的变化不同，借助于本发明基于粉煤灰掺量评估粉煤灰泡沫混凝土抗压强度的方法可以精确评估上述粉煤灰泡沫混凝土的抗压强度。
