The invention relates to the technical field of aerated bricks, in particular to an aerated brick and a preparation method thereof. The preparation method comprises the steps that a) mixing raw materials according to a ratio, and stirring to form slurry; b) adding aerated aluminum powder into the slurry, stirring, and pouring into a mold frame; c) performing gas forming and initial setting so thatthe slurry is set to form a green body; d) cutting the green body; e) performing autoclaved curing for 2 hours; f) performing natural maintenance. The raw materials are improved; silicon dioxide micro-powder and brick residues are added into the raw materials, dissolution of silicon dioxide can be accelerated in the earlier stage, hydration products can be conveniently generated as soon as possible, the brick residues are added into the raw materials after being smashed, a crystallization mechanism can be formed through crystal growth of hydration products such as hydrated calcium silicate inthe brick residues, and therefore, the silicon dioxide micro-powder and brick residues facilitate time shortening for autoclaved curing, and the production efficiency is improved.
本发明涉及加气砖技术领域，尤其涉及一种加气砖及其制备方法，a、将原料按照一定配比混合搅拌，得到料浆；b、料浆中投入加气铝粉并搅拌，浇注在模框中；c、发气初凝，料浆凝固为坯体；d、切割坯体；e、蒸压养护2小时；f、自然养护，本发明通过对原料的改进，在原料中添加二氧化硅微粉、砖渣，可以在前期加快二氧化硅的溶解，便于尽快生成水化产物，砖渣粉碎后加入原料中可以利用砖渣中的水化硅酸钙等水化产物晶体长大形成结晶机构，两者均有利于缩短蒸压养护的时间，从而提高生产效率。
