Abstract

The invention discloses a method for producing an energy-saving environmental-friendly high-performance autoclaved aerated concrete building block. The method comprises the following steps: A, preparing mortar; B, preparing and casting materials, namely, precisely weighing and mixing mortar, a cementing material, quick lime, an air entraining agent and water so as to prepare slurry under the control of discharge holes, conveying equipment and valves of respective cabins or storage tanks by virtue of electronic weighing; C, performing static leaving and maintenance, namely, sufficiently stirring the mixed slurry, discharging a mixture to a mold frame, and when a blank meets cutting strength, pulling the blank to a thermal static leaving chamber; D, performing demoling and cutting; E, performing autoclaved curing; F, performing inspection, packaging and storage, namely, stacking and packaging aerated blocks after autoclaved curing, taking samples for inspection, and delivering the blocks after inspection qualification. The building block disclosed by the invention is energy-saving and environmental-friendly, main performance indexes such as strength, size deviation, heat conduction coefficients and freezing resistance of the building block are prior to standards of national superior products, and the product quality stability can be improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an energy-saving and environment-friendly production method of high-performance autoclaved aerated concrete blocks. Background technique [0002] The production of aerated concrete blocks does not need to waste a lot of cultivated land, saves land resources, and has a wide range of raw materials; the blocks produced (1) are used as load-bearing walls (interior and exterior walls) of buildings with three floors and below; (2) can be used for steel structures , Filling of inner and outer walls of frame structure; (3) It can be used for roof insulation; (4) It can be used for building composite outer walls; (5) It can be used for fire protection of steel structures. Aerated concrete blocks have strong plasticity, can be planed and sawed, and have very good processing characteristics, so their application prospects are very good. However, due to the large deviation in the appearanc...
