Abstract

The invention discloses a hot-press forming coal gangue and building rubbish plate, which belongs to the technical field of building material preparation. The hot-press forming coal gangue and building rubbish plate consists of a surface material layer and a middle material layer, wherein the surface material layer is prepared from the following substances: 100 parts of coal gangue, 5 to 20 parts of alkali excitants, 30 to 50 parts of water, 100 to 300 parts of building rubbish and 0.1 to 1.2 parts of alkali-resistant fiber; the middle material layer is prepared from the following substances: 100 parts of coal gangue, 5 to 20 parts of alkali excitants, 20 to 40 parts of water, 400 to 1000 parts of building rubbish and 0.5 to 2.0 parts of alkali-resistant fiber. The coal gangue and the building rubbish are used as raw materials for plate preparation; the characteristics of low cost and wide sources are realized; in addition, the usage amount of the coal gangue is great; the utilization rate is high; waste materials are changed into valuable materials; the prepared plate has the advantages of light weight, high impact resistance, high toughness, low shrinking percentage, good fatigue resistance performance, high anti-carbonization capability and good durability.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a hot-pressed gangue construction waste plate. 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] Coal gangue contains a large amount of clay minerals. After being calcined at a certain temperature, it has a certain pozzo...
