Environment-friendly durable mixed type sintered hollow brick and preparation method thereof
The invention discloses an environment-friendly durable mixed type sintered hollow brick which is prepared from the following raw materials in parts by weight: 70-77 parts of a treated coal gangue shale mixed powder material, 2-3 parts of coke dust, 3-5 parts of barium carbonate, 48-52 parts of coal ash, 3-5 parts of sodium sulfate, 5-8 pars of coal ash and 9-10 parts of water. Due to addition of the treated coal gangue shale mixed powder material, the plasticity index of the mixed material can be increased, the brick blank can be relatively dense, and the strength and the durability of the brick blank are improved; due to addition of coal ash as packing, the energy can be saved, and the environment can be protected; due to addition of barium carbonate, the frost separation phenomenon can be reduced; the hollow brick prepared in a sintering manner is environment-friendly and good in durability, the coal resource can be saved, the self-weight of a construction structure can be reduced, and the functions of buildings can be improved.
