Abstract

The invention discloses a hot-pressing forming fly ash and building garbage sheet material belonging to the technical field of preparation of building materials. The hot-pressing forming fly ash and building garbage sheet material consists of a surface material layer and a middle material layer, wherein the surface material layer is made from the following substances of 100 parts of fly ash, 5-20 parts of an alkali activator, 30-50 parts of water, 100-300 parts of building garbage and 0.1-1.2 parts of alkali-resistant mineral wool; and the middle material layer is made from the following substances of 100 parts of fly ash, 5-20 parts of an alkali activator, 20-40 parts of water, 400-1000 parts of building garbage and 0.5-2.0 parts of alkali-resistant mineral wool. According to the hot-pressing forming fly ash and building garbage sheet material disclosed by the invention, the fly ash and the building garbage are used as raw materials for preparing the sheet material, and have the characteristics of being low in price and broad in sources; besides, the usage quantity of the fly ash is large, the utilization rate of the fly ash is high, and waste is turned into wealth; and therefore, the prepared sheet material has the advantages of being light in weight, high in shock resistance, high in tenacity, low in contraction rate, good in fatigue resistance, high in carbonization resistant capacity and good in durability.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a hot-pressed fly ash construction waste board. Background technique [0002] With the acceleration of the urbanization process and the continuous development of the economy, a large number of old buildings have been demolished, and the disposal of abandoned bricks, reinforced concrete fragments and other construction waste has become a social issue worthy of more and more attention. However, if it is simply landfilled, it will not only affect the urban environment and waste land resources, but also cause a huge waste of energy and resources. Using construction waste to prepare new construction waste panels can not only effectively treat waste, but also meet the development requirements of current building materials. [0003] Fly ash is a powdery substance that is separated and collected from the flue gas after coal combustion through a dust coll...
