Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the examples.

[0021] A production process for a high-strength aerated concrete slab, comprising the following process steps:

[0022] 1) Slag pretreatment: Dry the slag particles until their water content is less than 2%, then add them to the mill to grind them into slag powder with a particle size of less than 200 mesh, put the slag powder into the tank for storage; improve the activity of slag by grinding , to better participate in the hydration reaction.

[0023] 2) Preparation of premixed slurry: add the slag powder prepared in step 1) with 60-80 parts by weight and 20-40 parts by weight of water in a 10-cubic mixing tank and stir for 20 minutes to obtain a water content of 20-40% mixed slurry, and then transport the mixed slurry to a 50 cubic material storage tank and continue to stir for 1 hour to ensure that the slag powder and water are fully dissolved to obtain a premixed slu...

Abstract

The invention discloses a production process of a high-strength aerated concrete slab, belongs to the technical field of preparation of aerated concrete slabs, and solves the technical problems of limited resources, insufficient finished product strength, poor apparent quality and the like of an existing aerated concrete slab. According to the technical scheme, the production process of the high-strength aerated concrete slab comprises the following process steps that (1) slag is pretreated; (2) a pre-mixed slurry is prepared; (3) a slag slurry is prepared; (4) stirring and pouring are achieved; (5) standing is achieved; (6) cutting is achieved; (7) steam curing and warehousing are achieved; and (8) finished product detection is achieved. According to the production process of the high-strength aerated concrete slab, the prepared aerated concrete slab has the advantages of being high in strength, good in performance, environmentally friendly and the like.

Description

technical field [0001] The invention belongs to the technical field of air-entrained concrete slab preparation, and in particular relates to a production process of a high-strength aerated concrete slab. Background technique [0002] The autoclaved aerated concrete slab has high construction efficiency, good sound insulation and thermal insulation effect, and is the most matching enclosure material for steel structures and concrete structures that meets the requirements of prefabricated buildings. At present, domestic autoclaved aerated concrete slabs are mainly sand and fly ash aerated slabs. Among them, the raw materials for the production of sand aerated concrete slabs are mainly sand, lime, and cement. The source of sand is mainly close to rivers, and resources are limited. Due to the instability and low activity of fly ash itself, the fly ash aerated concrete board is significantly different from the sand aerated board in terms of pore structure, finished product streng...
