Problems solved by technology

However, when the residual slurry of pipe piles is reused, when the residual slurry is transported from the pipe pile factory to the downstream enterprise - the concrete production enterprise, it is very easy to produce hydration reaction, solidify and cannot be used

Embodiment 1

[0048]The domestic waste incineration slag concrete porous brick made of pipe pile residual pulp is prepared from pipe pile residual slurry, domestic waste incineration slag, cement, fly ash and stone chips. Among them, the mass percentage of pipe pile slurry, domestic waste incineration slag, cement, fly ash, and stone chips accounted for by the raw materials of pipe pile slurry, domestic waste incineration slag, cement, fly ash, and stone chips is: pipe pile slurry 20%, domestic waste incineration slag 28%, cement 0.8%, fly ash 15%, stone chips 36.2%.

[0049] The residual slurry of pipe piles is provided by the adjacent pipe pile factory. The remaining slurry of pipe piles is mixed with sugar retarder half an hour after going offline. The ambient temperature was 15 o c. Before adding the retarder, adjust the concentration of the residual slurry of the pipe pile to 10%, and then add 0.8kg retarder to the 1T residual slurry. The amount of the retarder needs to be used up w...

Abstract

The invention relates to a preparation process of a concrete porous brick prepared from tubular pile residual slurry and waste incineration slag. The preparation process comprises the following steps: firstly, pretreating raw materials, including delayed coagulation of tubular pile residual slurry, sorting and grinding treatment of domestic waste incineration slag and direct use of fly ash, cement and stone chips; secondly, stirring and mixing according to a set ratio; thirdly, filling a brick mold cavity with the mixed material by adopting a brick making molder and molding in a ramming manner; and finally, carrying out standing curing the molded concrete porous bricks and a bottom supporting plate together in a standing curing chamber for not less than 1 day, then transferring to a maintenance chamber spraying water for maintenance for 10-14 days, and finally transferring to a concrete porous brick stacking field and naturally maintaining for 28 days to obtain a concrete porous brick finished product. By adopting effective components in the tubular pile residual slurry and the waste incineration slag to produce the tubular pile residual slurry-waste incineration slag concrete porous brick, the preparation process has the advantages of not only reducing and avoiding emission of waste slag and waste liquid left over in industrial production so as to prevent secondary pollution, but also saving lots of land stacking cost and treatment expenses.

Description

technical field [0001] The invention belongs to the technical field of building bricks, and relates to a process for preparing concrete porous bricks made of waste incineration slag from pipe pile residues, and more specifically to a method of using industrial waste liquid (pipe pile residue) instead of cement, and using industrial waste residue (life Garbage incineration slag) partly replaces the aggregate, and at the same time adds fly ash and stone chips to produce concrete porous bricks. Background technique [0002] During the production process of pipe piles, a large amount of highly alkaline suspension containing cement, fine sand and water—pipe pile residual slurry is produced in the inner cavity of the pipe wall. Enterprises usually directly transport the solidified slurry to the landfill or dump it at will, which seriously pollutes the surrounding environment. Municipal domestic waste is increasing at an annual rate of 8-10%. Power plants use the calorific value o...
