Embodiment 1

[0026] The second step: crush the construction waste to a particle size of less than 15mm, use a feeder to transport the crushed construction waste and all RAP to the automatic proportioning equipment for batching and mix evenly.

[0027] Step 3: Transfer the mixed material to the twin-shaft mixer, first stir evenly for 2-3 minutes, then add cement and water, set the speed at 60r / min, and fully stir for 5-7 minutes.

[0028] Step 4: Transport the mixed material evenly stirred in the third step to the hopper of the molding machine, feed the material into the mold from the hopper of the molding machine, and shape the mixed material by the molding machine. The molding pressure is 15-20MPa .

[0029] Step 5: Transport the formed bricks to the pallet, and transport them to the curing room by the conveyor belt for curing. The curing conditions are 25°C and 75% humidity. After one week of curing, the asphalt bricks will be obtained.

[0030] Step 6: Weigh 90 parts of epoxy resin, 25...

Abstract

The invention discloses a colorful pavement brick and a preparation method thereof. The colorful pavement brick is formed by compounding a base layer, a colorful surface layer and a covering layer, wherein the base layer of the colorful pavement brick is completely made of reclaimed building rubbish and RAP, so that waste materials are sufficiently utilized; the colorful surface layer is arranged on the base layer, so that a great quantity of resources are saved, and the preparation is simple. The colorful pavement brick is free from maintenance, is high in corrosion resistance and weather resistance, is economical and environmentally friendly, and beautifies the environment. The colorful pavement brick has the characteristics that the compressive strength is 15.8-16.7MPa, the wear resistant length is 7.6-8.4mm, and the freezing and thawing strength loss rate is 4.1-4.7%.

Description

technical field [0001] The application belongs to the field of building materials, in particular to a colored pavement brick and a preparation method thereof. Background technique [0002] With the rapid development of my country's transportation industry, the scale of my country's expressways has also increased. In recent years, the development of my country's expressways has changed from centralized construction to large-scale maintenance, which has led to the emergence of a large number of RAPs. In addition, the rapid development of my country's construction industry has also produced a large amount of construction waste. The generation of a large amount of construction waste and RAP not only occupies a large area of ​​land, but also costs a lot to dispose of these waste materials and is also very difficult to deal with. Random dumping wastes a lot of resources and causes serious environmental pollution. The recycling and utilization of waste materials is imminent. ...
