Abstract

The invention discloses a plate prepared from slag and construction waste through hot press molding, and belongs to the technical field of construction material preparing. The plate is composed of a surface material layer and a middle material layer, wherein the surface material layer is prepared from 100 parts of slag, 5-20 parts of an alkali-activator, 30-50 parts of water, 100-300 parts of construction waste and 0.1-1.2 parts of alkali-resistant fibers, and the middle material layer is prepared from 100 parts of slag, 5-20 parts of an alkali-activator, 20-40 parts of water, 400-1,000 parts of construction waste and 0.5-2.0 parts of alkali-resistant fibers. According to the plate, the slag and the construction waste are adopted as the raw materials for preparing the plate, the advantages of being low in cost and wide in source are achieved, a large amount of the slag is used, the utilization rate of the slag is high, the waste materials are changed into things of value, and the prepared plate has the advantages of being small in mass, high in impact resistance and toughness, low in shrinkage rate, good in fatigue resistance, high in anti-carbonization 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 slag 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] Slag is the residue of ore after beneficiation or smelting. Its large-scale stockpiling occupies a large amount of land, and ...
