Embodiment Construction

[0029] As shown in Figure 1, it is a process flow chart of the production method of the present invention. The raw material formula of an embodiment of this air-entrained concrete block and parts by weight thereof are:

[0030] 60kg of fly ash, 20kg of lime, 8kg of gypsum, 12kg of cement, 6kg of composite air-generating agent, 1.5kg of high-efficiency fly ash activator, 2.5kg of composite stabilizer and appropriate amount of water.

[0031] 2. The production method of aerated concrete block according to claim 1, characterized in that: the process flow of the production method is:

[0032] (1) Fly ash pretreatment is to dehydrate and concentrate fly ash with a moisture content greater than 30%. The slurry storage tank is used for natural sedimentation and dehydration, or a vacuum dehydrator is used for dehydration, and the fineness requirement is 0.045. mm square hole sieve balance is not more than 30%, and weigh 60kg;

[0033] (2) For the crushing of lime and gypsum, use a c...

Abstract

The aerated concrete block is produced with fly ash 50-65 weight portions, lime 18-22 weight portions, gypsum 6-10 weight portions, cement 7-16 weight portions, composite gas former 4-8 weight portions, efficient fly ash activator 1-2 weight portions, composite stabilizer 1.5-3 weight portions and water in proper quantity; and through the production process including the steps of fly ash pre-treatment, crushing lime and gypsum, pre-activating fly ash, mixing the materials to prepare slurry and pouring, pre-curing, cutting, and steam curing to obtain the product. The production process adopts pre-activating and secondary activating and composite stabilizer, and the aerated concrete block product has low cement consumption, low cost and high strength.

Description

technical field [0001] The invention relates to a reverse building wall material and a production method thereof, in particular to an aerated concrete block and a production method thereof. Background technique [0002] The traditional aerated concrete block is a light and porous building material. It is made of cement, lime, slag, fly ash, sand, gas-generating materials, etc., after grinding, batching, pouring, cutting, steaming It has the advantages of light weight, good thermal insulation performance and machinability, but it has a single variety, high cost, low strength and limited application range. [0003] In view of this, in order to overcome the above-mentioned shortcoming, the creator finally has the present invention to produce through research and development according to his actual experience and technical ideas. Contents of the invention [0004] The present invention provides an aerated concrete block and its production method to solve the technical problem...
