Abstract

The invention relates to a novel environment-friendly building brick and a preparation method, and belongs to the technical field of waste disposal. The building brick comprises silicate cement, gypsum, a GCY activating agent, an MSZ168-C additive, coarse slag, fine slag and magnetized water. The preparation method comprises steps as follows: firstly, slag discharged by a slag waste incineration power plant is subjected to a series of pretreatment of hydrolytic tank washing, crushing screening, magnetic separation, flotation separation and screening of 3-15 cm particles, the slag and the MSZ168-C additive are added into an agitation tank by using a forced mixer according to a set proportion, the GCY activating agent is diluted in the magnetized water magnetized by a magnetizer, the mixture and cement are jointly added for agitation, and maintenance is performed after compression molding, so that a finished product is obtained. According to the novel environment-friendly building brick and the preparation method, the slag is prepared into a mold brick without firing, the preparation time is shortened, the burning energy consumption is reduced, emission of harmful gas in a burning process is avoided, and the environment protection effect is remarkable; and the manufactured brick is high in strength, light in weight and good in thermal insulation property, and the requirement for light mass, energy conservation and thermal insulation of wall materials of a modern building can be met.

Description

technical field [0001] The invention relates to a building brick, in particular to an environmentally friendly brick produced by using slag produced by burning garbage and a preparation method thereof, belonging to the technical field of waste treatment. Background technique [0002] As the basic construction continues to heat up, the demand for building bricks is also increasing. The existing brick-making technology is to use clay to burn bricks, and clay to burn bricks will cause a lot of damage to basic farmland. Therefore, using the principle of waste reuse, it has become a top priority to produce energy-saving and waste-friendly environmentally friendly bricks. [0003] A certain amount of slag will be produced after incineration of garbage in the domestic garbage incinerator, and the amount of slag produced by the grate furnace is about 20% of the weight of the garbage. Slag is generally landfilled, which not only occupies land resources, but also brings potential saf...
