Coal gangue and shale hollow brick with excellent frost resistance and manufacturing method thereof
The invention discloses a coal gangue and shale hollow brick with excellent frost resistance. The coal gangue and shale hollow brick with excellent frost resistance is characterized by being prepared from the following raw materials in parts by weight: 70-73 parts of mixed powder of treated coal gangue and shale, 50-54 parts of pulverized fuel ash, 9-11 parts of saw dust, 4-6 parts of red mud, 3-5 parts of sodium sulfate, 2-3 parts of sodium chloride, 4-6 parts of spent pulping liquor and 9-10 parts of water. Compared with the prior art, the coal gangue and shale hollow brick disclosed by the invention has the advantage that the components are matched scientifically and reasonably; due to the addition of the mixed powder of treated coal gangue and shale and the ball-milled pulverized fuel ash, the plasticity index of the coal gangue and shale hollow brick is increased, the cohesiveness of particles is improved, and the adobe is compact, is low in water absorption rate and cracks less in the drying process; due to the addedsodium chloride, the frost resistance of the coal gangue and shale hollow brick is improved; due to the matched components, the coal gangue and shale hollow brick can be baked easily to have high cohesional strength and good frost resistance; and because the saw dust is burnt away in the baking process, the coal gangue and shale hollow brick is light in weight.
