Lightweight aggregate concrete solid brick and production process thereof
The invention relates to the technical field of concrete solid bricks, in particular to a lightweight aggregate concrete solid brick and a production process thereof, and the production process comprises the following production process steps: S1, preparing raw materials: fly ash, coal cinder, cement and an additive according to a ratio of (6-8): (3-4): (1-2), and adding a proper amount of additive; s2, when the raw materials are put into a stirrer, firstly putting the cement, the fly ash and the additive aqueous solution, then carrying out dry stirring for 5-10 min, adding the aggregate, carrying out dry stirring for 2-4 min, then adding water, and carrying out wet stirring for 5-8 min; s3, carrying out pressure forming on the mixed raw materials by adopting a vibration pressure forming machine; the coal cinder is stored in the open air for 30-35 days and then crushed, the crushed coal cinder is stored for 3-4 days, and water is sprayed regularly, so that sulfide and overburnt lime are hydrolyzed and digested, the brick body can be effectively prevented from expanding and bursting, the particle size of the crushed coal cinder is smaller than 15 mm, the particle size of the crushed coal cinder is 95-98% when the particle size of the crushed coal cinder is smaller than 10 mm, and the compactness of a product during forming can be effectively guaranteed; the light aggregate solid brick is prepared from the fly ash and the coal cinder waste, so that huge social benefits are generated.
本发明涉及混凝土实心砖技术领域，具体为一种轻集料混凝土实心砖及其生产工艺，包括以下生产工艺步骤：S1,原材料：粉煤灰、煤渣、水泥和添加剂，其配比为：粉煤灰：煤渣：水泥是6～8：3～4：1～2，并添加适量添加剂；S2，将原材料投放到搅拌机时先将水泥、粉煤灰及外加剂水溶液投入，然后干搅拌5～10mi n，加入骨料干搅2～4mi n,再加水湿搅拌5～8mi n；S3，采用振动加压成型机对混合后的原材料进行加压成型；通过煤渣露天存放30～35d然后破碎，破碎后再存放3～4d并定期洒水，使硫化物和过烧石灰水解消化，能够有效的避免砖体膨胀爆裂，碎后粒径小于15mm，10mm粒径以下达到95～98％，能够有效的保证制品成型时的密实度；通过采用粉煤灰和煤渣废料制作轻集料实心砖产生了巨大的社会效益。
