Problems solved by technology

[0004] At present, in many domestic silt solidification projects, especially in the reinforcement foundation of tidal flat silt in coastal areas, the widely used structural foundation is still cement and lime reinforced crushed stone or sand and gravel. The implementation of such measures is becoming more and more restricted. In addition, for some areas that lack sand and gravel, this process requires a large am

Example Embodiment

[0016] Example

[0017] The nickel alloy slag of the following examples is water quenched slag, the fineness modulus is 2.8, and the gradation of compound II zone; cement: Conch Group P·O42.5 cement; slag: S95 grade, fly ash is tertiary ash; activator: All are industrial grade. When preparing the composite cured material, the activator can be uniformly mixed with other components as a solid phase component, or it can be formulated into a solution and added separately in proportion as a liquid phase component during use. The test soil is taken from a depth of 1.5 meters underground in the Xuwei New Area of ​​Lianyungang, which is tidal mud. The basic parameters of the mud are shown in Table 1.

Abstract

The invention discloses an environment-friendly nickel alloy slag composite curing material for flat sludge. The environment-friendly nickel alloy slag composite curing material is composed of the following component in percentage by weight: 45.0-65.0% of nickel alloy slag, 5-10% of mineral powder, 10-18% of coal ash, 5-15% of cement, 15-27% of lime and 1-5% of salt excitant. The environment-friendly nickel alloy slag composite curing material for the flat sludge is simple in raw material, wide in raw material source, and scientific and rational; the raw materials of the environment-friendly nickel alloy slag composite curing material most are the nickel alloy slag which is difficult to consume and utilize industrially at present and industrial solid wastes such as slag and coal ash, so that the environment-friendly nickel alloy slag composite curing material for the flat sludge accords with the state environmental protection policy, and is capable of saving energy and reducing consumption, and besides, the solidified soil is excellent in mechanical properties and water stability.

Description

[0001] technical field [0002] The invention relates to a composite solidified material for beach mud. In particular, it is an environment-friendly nickel alloy slag composite solidification material for beach mud. Background technique [0003] Nickel alloy slag belongs to non-ferrous metallurgical industrial waste, which is a solid waste discharged after smelting semi-finished products or primary ores to extract purpose metals such as nickel-iron alloys. Nickel alloy slag is divided into pyrometallurgical waste slag and hydrometallurgical waste slag. Pyrometallurgical nickel alloy slag is the residue after the primary minerals are melted and separated into useful components; hydrometallurgical nickel alloy slag mainly refers to the residual waste residue after the primary minerals are extracted or electrolyzed to obtain the target metal. As a non-ferrous metal smelting process with multiple physical and chemical processes, the residue discharged after smelting the t...
