Aerated concrete block prepared by replacing part of ground fine sand with waste ceramic polished sludge and preparation method of aerated concrete block
The invention relates to the field of concrete materials, and discloses an aerated concrete block prepared by replacing part of ground fine sandwith waste ceramic polished sludge and a preparation method thereof. The aerated concrete block is prepared from, by weight, 45-115 parts of cement with the average particle size being 30-60 [mu]m and the strength grade being not smaller than 42.5, 80-140 parts of quick lime with the average particle size of 35-70 [mu]m and the digestion time of 10-30 minutes, 5-30 parts of gypsum with the average particle size of 20-80 [mu]m, 180-420 parts of waste ceramic polishing sludge with the average particle size of 1-100 [mu]m, 90-210 parts of the ground fine sand with the average particle size of 50-130 mu m, 0.4-1.0 part of a foaming agent and 100-150 parts of water. Wherein the pretreatment of the waste ceramic polishing sludge is characterized in that waste ceramic polishing sludge slurry with the mass concentration of 45-55wt% is mixed with the remaining raw materials. The aerated concrete block prepared from the waste ceramic polishing sludge instead of part of the ground fine sand is relatively low in overall price, high in waste utilization rate, high in strength, uniform in pore distribution, good in freeze-thaw resistance, small in dry shrinkage performance and suitable for development and application of green and energy-saving building materials.
本发明涉及混凝土材料领域，公开了利用废弃陶瓷抛光淤泥取代部分磨细砂制备的加气混凝土砌块及其制备方法，该加气混凝土砌块由以下重量份数的原料制成：平均粒径30～60μm、强度等级不小于42.5的水泥45～115份，平均粒径35～70μm、消解时间10～30分钟的生石灰80～140份，平均粒径20～80μm的石膏5～30份，平均粒径1～100μm的废弃陶瓷抛光淤泥180～420份，平均粒径50～130μm的磨细砂90～210份，发气剂0.4～1.0份，水100～150份；其中，废弃陶瓷抛光淤泥预处理为质量浓度45～55wt％的废弃陶瓷抛光淤泥浆料后再与余下原料混合。该利用废弃陶瓷抛光淤泥取代部分磨细砂制备的加气混凝土砌块整体价格相对低廉，废弃物利用率高，强度高，气孔分布均匀，抗冻融性能好，干缩性能小，适合绿色节能建材的发展与应用。
