利用粉煤灰生产加气混凝土轻质建筑材料是合理利用粉煤灰,变废为宝,化害为利的良好途径。这对于开辟加气混凝土的新品种,为社会主义建设提供多种建筑材料也具有重要的意义。粉煤灰加气混凝土国外已有生产相应用;国内也有一些单位作过许多研究,有的还建有试点建筑。但是,某些生产工艺与制品性能问题尚未彻底解决,特别是浇注稳定性差,制品裂缝比较严重。因此,粉煤灰加气混凝土的研究有待于深入进 The use of fly ash to produce aerated concrete lightweight construction materials is a good way to rationally use fly ash, turn waste into treasure, and harm harm. This is of great significance to opening up new varieties of aerated concrete and providing a variety of building materials for socialist construction. Fly ash aerated concrete has been used in production abroad; there are also some domestic units that have done a lot of research, and some have built pilot buildings. However, some production processes and product performance problems have not yet been completely resolved, especially the poor casting stability, cracks in the products are more serious. Therefore, the study of fly ash aerated concrete needs to be further studied.
