The invention relates to the technical field of mineral admixtures, and particularly relates to an environment-friendly high-performance mineral admixture and a preparation method and application thereof.
Background
In current traffic construction, the use of cement stabilized macadam as a semi-rigid base course is the most common pavement structure. The cement stabilized macadam base has higher compressive strength and bearing capacity, has certain bending tensile strength, and has the characteristic of continuous increase along with the increase of the age. Therefore, the asphalt pavement adopting the cement stabilized macadam base usually has smaller deformation and stronger load diffusion capacity, thereby improving the capacity of resisting the fatigue damage of the driving load of the pavement. However, a large number of engineering practices have shown that cement stabilized macadam foundations suffer from the following disadvantages:
adding 3-6% cement into the water-stable base layer. As a high-energy consumption material, the cement is mainly produced by limestone (calcium carbonate). Limestone needs to be mined during the collection process, so that the natural landscape and green vegetation of a mountain can be seriously damaged, and a large amount of greenhouse gas and dust can be discharged during the collection process, thereby causing pollution to the environment and the atmosphere. In addition, the production of cement by using limestone is a process with high energy consumption, high pollution and high emission;
secondly, the shrinkage cracking of the cement stabilized macadam base can cause the reflective cracks of the asphalt pavement. The use survey of the domestic constructed highway shows that the early pavement damage phenomena of cracking, rutting, oil flooding, loosening, pit and water damage and the like occur on a plurality of semi-rigid pavements for 1 to 3 years even if the vehicles are communicated for a long time;
thirdly, the average manufacturing cost of the cement stabilized macadam base is about 300 yuan/m3The construction cost is high.
Therefore, selecting a suitable cementitious material to replace cement, either in whole or in part, is an effective means to solve the above problems.
In view of this, the invention is particularly proposed.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
In current traffic construction, the use of cement stabilized macadam as a semi-rigid base course is the most common pavement structure. However, a number of engineering practices have shown that cement stabilized macadam substrates suffer from a number of disadvantages, particularly problems associated with the use of cement and limestone. Therefore, selecting a suitable cementitious material to replace cement, either in whole or in part, is an effective means to solve the above problems.
The discharge amount of industrial solid wastes in China is 30 hundred million tons every year, wherein the discharge amount of the industrial solid wastes comprises a large amount of slag, fly ash and red mud. The discharge and the stacking of the materials cause the problems of waste of land resources and environmental pollution. However, the materials have certain activity, can excite certain strength under the action of an alkali activator, are suitable for replacing cement in cement stabilized macadam, reduce the construction cost on one hand, and reduce the generation of base cracks by reducing the using amount of the cement on the other hand, thereby prolonging the service life of roads.
In order to achieve the above object of the present invention, the following technical solutions are adopted.
In a first aspect, an embodiment of the present invention provides an environment-friendly high-performance mineral admixture, which is composed of the following components in parts by weight: 400 parts of slag, 400 parts of fly ash, 500 parts of red mud, 100 parts of alkali excitant and 1-3 parts of water reducing agent.
The embodiment of the invention provides an environment-friendly high-performance mineral admixture, which is prepared by adopting the following raw materials of a large amount of wastes which are produced in the current industry, such as byproducts in a blast furnace ironmaking process: slag, industrial waste slag discharged from a power plant using coal as a raw material: fly ash and solid waste produced in the process of preparing alumina by using bauxite: red mud. The 3 materials are used as raw materials for preparing the environment-friendly high-performance mineral admixture. The reason is that: slag itself has a good latent hydraulic activity and is easily activated by alkali, while the activity of other aluminosilicate materials is mostly difficult to be activated by alkali and to obtain good properties like alkali slag cement. Sodium oxide and potassium oxide in red mud are often combined as alkali compounds, so red mud is a raw material of alkali-binding material that can replace part of slag. The fly ash is naturally acidic, and the active ingredients of the fly ash can be excited under alkaline conditions. The 3 materials are excited to have certain strength under the action of the alkali activator, are suitable for replacing cement in cement stabilized macadam, reduce the construction cost on one hand, and reduce the generation of base cracks by reducing the cement consumption on the other hand, thereby prolonging the service life of roads.
In an alternative embodiment, the environment-friendly high-performance mineral admixture is composed of the following components in parts by weight: 350 parts of slag, 420 parts of fly ash, 480 parts of red mud, 120 parts of alkali excitant and 1-3 parts of water reducing agent.
In an alternative embodiment, the red mud should be dried, otherwise, the drying treatment at 50-60 ℃ should be carried out.
In an alternative embodiment, the alkaline activator comprises one or more of calcium hydroxide, sodium sulfate, and calcium sulfate.
In an alternative embodiment, the water-reducing agent is a polycarboxylic acid type high performance water-reducing agent.
In an optional embodiment, the specific surface area of the environment-friendly high-performance mineral admixture is 350-500m2Per kg, with a fineness of 1.0-3.5%.
In an alternative embodiment, the environmentally friendly high performance mineral admixture has a 28d mortar compressive strength of 40 to 50 MPa.
