The invention relates to the technical field of aerated bricks, in particular to a production method of aerated bricks, which comprises the following steps: a) proportionally mixing and stirring raw materials to obtain slurry; b) adding aerated aluminum powder into the slurry, stirring, and pouring into a mold frame; c) performing gas generation and initial setting; d) cutting a green body; e) spraying cement paste; f) performing autoclaved curing; g) performing natural maintenance. Silicon dioxide micro-powder and the initially set slurry are added into the raw materials, generation of hydration products can be facilitated, and hydrated product crystals such as hydrated calcium silicate in the initially set slurry can be used as crystal nucleuses and grow up quickly to form a crystallization mechanism, and therefore, the silicon dioxide micro-powder and the initially set slurry facilitate time shortening for autoclaved curing, and the production efficiency is improved. After sprayingwith the cement paste, the cement paste on the surface and the aerated bricks are combined to form a surface layer which is higher in strength and not prone to dusting, and the surface layer can be bonded with mortar more easily in a wall building process.
本发明涉及加气砖技术领域，尤其涉及加气砖的生产方法，a、将原料按照配比混合搅拌，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；d、切割坯体；e、喷淋水泥浆；f、蒸压养护；g、自然养护，本发明在原料中添加二氧化硅微粉、初凝的料浆，可以便于促进生成水化产物，初凝的料浆中的水化硅酸钙等水化产物晶体可以作为晶核，迅速长大形成结晶机构，两者均有利于缩短蒸压养护的时间，从而提高生产效率，喷淋水泥浆后，使得在表面处水泥浆与加气砖结合，形成一个强度更高、不易起粉末的表层，在砌墙时，该表层也更容易与砂浆粘结。
