Preparation process of aerated concrete block

Abstract

The invention discloses a preparation process of an aerated concrete block. The process comprises the following steps: weighing three parts of aluminum powder paste with different weights in parts by weight, and respectively mixing and stirring the aluminum powder paste with three parts of sodium sulfate, sodium abietate, fly ash, bagasse, lime powder and gypsum powder which are equal to each other, so as to prepare a first lightweight aggregate, a second lightweight aggregate and a third lightweight aggregate; preparing a first mixture; preparing an additive; respectively preparing a first building block raw material, a second building block raw material and a third building block raw material from the first lightweight aggregate, the second lightweight aggregate, the third lightweight aggregate, the first mixture, cement and an additive; sequentially injecting the first building block raw material, the second building block raw material and the third building block raw material into a concrete building block mold; carrying out gas expansion treatment to obtain a building block blank body; and carrying out steam curing on the building block blank body to obtain the formed building block. According to the technical scheme, the problem that the strength deviation of all parts of the aerated concrete block is large due to the fact that the sizes and the number of air holes of the aerated concrete block are not uniform is effectively solved.

Description

technical field [0001] The invention relates to the technical field of aerated concrete blocks, in particular to a preparation process of aerated concrete blocks. Background technique [0002] Aerated concrete block is a new type of building material that is lightweight, porous, thermally insulated, good in fire resistance, can be nailed, sawed, planed, and has a certain degree of earthquake resistance. It is also an excellent new type of building material. Different raw materials, different conditions to tailor-made, raw materials can choose river sand, fly ash, ore, etc., according to local conditions, and can be used for waste, which is beneficial to environmental protection and truly turns waste into treasure. [0003] At present, when preparing aerated concrete blocks, after the pouring is completed, in the process of gas generation, because the lower part of the raw material of the block is under the pressure of the upper part, the pores generated in the lower part wil...
