Problems solved by technology

However, the production process of autoclaved sand aerated concrete blocks is highly polluted, and its strength increases with the increase of bulk density. If high strength is required, its bulk density must be increased.
After decoration, there are many common quality problems and it is difficult to deal with them

Abstract

The invention discloses a method for producing autoclaved aerated concrete building blocks, which relates to the technical field of concrete building blocks. The method comprises the following steps: performing burdening, metering, stirring, casting, primary maintenance, cutting, and autoclaving on the mortar, lime, cement and phosphogypsum to prepare the autoclaved aerated concrete building blocks. The produced autoclaved aerated concrete building blocks have good processing performance, steel bar can be added during a production process, large convenience and flexibility can be provided to construction, masonry manual work is saved, on-site construction progress is accelerated, construction efficiency is increased, the preparation method has the advantages of easy and convenient operation, and environment pollution can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of concrete block processing, in particular to a method for preparing an autoclaved sand aerated concrete block. Background technique [0002] In recent years, the state has gradually reduced the use of clay sintered bricks for soil protection, and the policy of prohibiting the use of clay sintered bricks in some areas has been launched and is being implemented. A series of masonry materials such as lime-sand bricks, hollow bricks, and cement are used in construction. Autoclaved sand aerated concrete block is a new type of building material that is lightweight, porous, thermal insulation, good fire resistance, can be nailed, sawed, planed and has certain earthquake resistance. However, the production process of autoclaved sand aerated concrete blocks is highly polluted, and its strength increases with the increase of bulk density. If high strength is required, its bulk density must be increased. After deco...
