Abstract

The invention discloses a steaming-free aerated brick prepared by utilizing construction waste. The steaming-free aerated brick is prepared from the following components in parts by weight: 20 to 30 parts of the construction waste, 30 to 60 parts of pulverized fuel ash, 30 to 50 parts of cement, 5 to 10 parts of desulfurized dihydrate gypsum, 3 to 8 parts of quicklime, 0.5 to 1 part of aluminum powder paste, 4 to 6 parts of ultra-light ceramic particle, 1 to 5 parts of silica aerogel, 1 to 2 parts of naphthyl sulfonate formaldehyde condensate, 2 to 5 parts of retarding agent and 30 to 50 parts of water. The invention also discloses a preparation method of the steaming-free aerated brick. The steaming-free aerated brick made by using the method is light in weight, good in heat preservation performance and heat insulation performance, high in shock resistance ability and excellent in compression resistance performance, and has certain high temperature resistance performance, good sound insulation performance and high adaptability; further, the preparation method is simple; the production cost is low.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to a non-steaming aerated brick prepared from construction waste. Background technique: [0002] Construction waste is produced in the process of building construction, maintenance or demolition, mostly solid waste. The comprehensive utilization of construction waste is of great significance for saving resources, improving the environment, improving economic and social benefits, and realizing optimal allocation of resources and sustainable development. The traditional treatment of construction waste is mainly as backfill material and reinforcement of soft soil foundation, etc., but its utilization rate is still very low compared with its output and stock, and new ways of utilization should be explored. As a traditional wall material, the use of fired clay bricks has been prohibited due to the waste of land and energy and environmental pollution in the process of production and us...
