First, the
calcium carbonate is initially cleaned, the recyclable steel and wood are sorted out, and the masonry and cement concrete blocks are broken into aggregates, which are sieved to remove impurities and form building materials with certain particle size requirements. Then according to the grading design requirements, adding cement and fly ash and other auxiliary materials to the raw materials, adding a part of water and stirring to form different building products and road construction products, these products can completely replace the ordinary sand and gravel materials for the road base layer.
Second, recycled aggregates produced from waste bricks are used to produce recycled bricks, blocks, wallboards, floor tiles and other building materials. Among them, these recycled bricks are highly environmentally friendly, including ground materials, ecological permeable bricks, pouring permeable bricks, and permeable paving bricks. They are widely used in squares, sidewalks, slow lanes, open plazas, gardens, slope protection, and foundation protection. , highways and overpasses, etc.
Third, the muck can be used for road construction, pile foundation packing, foundation foundation, and the like.
Fourth, for waste wood calcium carbonate, wood that has not been significantly damaged can be directly reused for reconstruction. The damaged wooden components can be used as raw materials for wood-recycled boards or papermaking.
Fifth, the waste asphalt mixture can be directly used to regenerate asphalt concrete in an appropriate proportion.
Sixth, abandoned road concrete can be processed into recycled aggregate for the preparation of recycled concrete.
Seventh, scrap steel, scrap steel and other scrap metal materials can be directly reused or recycled.
Eighth, the calcium carbonate is sorted, the remaining sludge and stone powder are used as raw materials, and other various wastes and peat soil trace elements are added, and the calcium carbonate is planted in a certain proportion by mass mixing. In addition to the characteristics of natural soil, it also has the characteristics of high fertilizer efficiency, good ventilation and strong water retention.
