Problems solved by technology

[0005] In the process of slag utilization in the prior art, the problem of the difference in water absorption between garbage slag and ordinary concrete aggregates is not considered. In the process of designing the mix ratio of various materials for garbage slag concrete, when determining the water consumption, the garbage slag is ignored. The problem of water absorption of the slag aggregate makes it impossible to fully mix the waste slag concrete. At the same time, the optimization of the mass ratio of the waste slag coarse aggregate to the total coarse aggregate in the concrete and the compressive strength of the concrete are not considered. The resulting concrete There is a gap between the water resistance and compressive strength of ordinary concrete. In addition, the stability and overall performance are not high
If it is not overcome, there will be safety hazards in the use of garbage slag concrete

Embodiment 7

[0087] Example 7 The dosage ratio of each material in concrete is based on the mass of the material required to prepare each cubic concrete, which is: the dosage ratio of each material in the concrete, and is calculated as: garbage 400kg of incineration power plant slag, 300kg of cement, 150kg of magnetized water, 260kg of sand, 1300kg of graded gravel with a particle size of 10-20mm, 3.3kg of water reducing agent, 20kg of GCY activator and 4kg of acrylic resin; the preparation method is as follows:

[0088] (1) Slag pretreatment: The slag discharged from the waste incineration boiler of the waste incineration power plant is washed by a hydrolysis tank to remove soluble salts, and then crushed and screened, magnetically separated, buoyantly sorted, and sieved to obtain a particle size of 3~ 5mm, the apparent density is 1996kg / m 3 waste slag coarse aggregate;

Abstract

The invention discloses a preparation method of garbage incineration power generation furnace slag concrete. According to the method, during a concrete preparation process, acrylic resin is added in two batches, magnetized water is added in three batches, and stirring is carried out four times. A construction material is prepared with garbage furnace slag, such that a resource is effectively recovered and utilized. The method is simple; preparation efficiency is high; and the production process is environment friendly. Through adjusting the ratio, concrete products with different strength grades can be obtained. The finally obtained concrete has the advantages of sufficient and fine mixing, good compressive strength, good water resistance, high stability, and good comprehensive performance.

Description

technical field [0001] The invention relates to a preparation method of concrete, in particular to a preparation method of waste incineration power generation furnace slag concrete, and belongs to the technical field of comprehensive utilization of solid waste resources. Background technique [0002] Waste incineration power generation technology is that waste is burned in an incinerator to release heat energy, and the waste heat is recovered for power generation. The use of waste incineration for power generation is one of the common harmless treatment methods for domestic waste, and it is an effective way to realize resource recycling. After the garbage enters the incinerator for incineration, a large amount of waste residue will be produced, which is called slag, and slag belongs to general waste. [0003] Relevant research data show that the main components in slag are slag, glass, ceramics, bricks, stones, etc., and also contain certain plastics, metal substances, and ...
