Abstract

The invention relates to the technical field of building materials, and discloses an energy-saving high-strength autoclaved sand-lime brick production and processing method. The autoclaved sand-lime brick comprises the following raw materials (by mass): 20%-30% of natural sand, 20%-30% of glass fragments, 20%-40% of quick lime, 20%-40% of fly ash, and 5%-15% of super absorbent resin particles. According to the energy-saving high-strength autoclaved sand-lime brick production and processing method, the raw materials are doped with the glass fragments to serve as the siliceous material, the glass fragments can be used for producing the autoclaved sand-lime brick, resources can be saved, pollution of the glass fragments to the environment can be reduced, and the purposes of energy conservation and high strength are achieved; meanwhile, the super absorbent resin is added into the raw materials, so that the curing time is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an energy-saving and high-strength autoclaved lime-sand brick production and processing method. Background technique [0002] Autoclaved lime-sand bricks are ordinary lime-sand bricks made of sand and lime as the main raw materials, pigments and admixtures are allowed, prepared from blanks, pressed into shape, and cured by high-pressure steam. Lime-sand brick is a new type of building material with mature technology, excellent performance and energy saving. It is suitable for load-bearing walls of multi-storey mixed structure buildings. However, the disadvantage of autoclaved lime-sand bricks is its unstable shrinkage. It will shrink greatly within 3 days after it is released from the oven, and it will not gradually stabilize until 60 days later. For cracking, it is necessary to take some anti-cracking measures when using it. [0003] There are following defects and ...
