Multifunctional composite mixed material and preparation process and application thereof

Abstract

The invention provides a multifunctional composite mixed material and a preparation process and application thereof. The multifunctional composite mixed material mainly comprises iron and steel smelting slag of steel plants, nickel-iron slag wastes of stainless steel plants, urban construction wastes, marble processing wastes, iron tailing powder and granite tailing powder. The mixed material can be used as a mate material for cement mate and S95 ore powder to replace part of existing construction materials. In addition, raw materials of the mixed material are extensive in source and cheap due to utilization of renewable resources; a preparation process is simple and short, logistic links and transport volume are reduced, and environmental friendliness and energy saving are realized due to canceling of a combustion drying procedure in the traditional process.

Description

technical field [0001] The invention relates to the field of building materials, in particular to the field of reuse of building materials prepared from various waste materials. Background technique [0002] The acquisition of mixed materials has long been that the active material is manufactured in one place, and the inactive material is in another place. The concrete mixing plant needs to pull these two different materials back to the mixing plant from different origins. This traditional manufacturing process has dominated the cement plant and concrete mixing plant industry for over 200 years. After decades of construction and development in developed countries, the period of rapid growth in infrastructure has long since ended. Developed countries have a small population, and the total consumption of cement plants and concrete for housing and infrastructure construction has been less than 50% of China's for ten consecutive years. In order to reduce the amount of cement us...

Problems solved by technology

Especially in the vicinity of the city, the secondary pollution caused by the use of the above-mentioned powdery items is a major problem in the current urban environmental protection management.

[0007] The transportation of the above-mentioned powdery articles requires special means of transportation, such as active materials and inactive materials are not manufactured in a factory, which increases the huge logistics flow, causes huge waste of energy, and huge environmental protection costs (currently, more water is used for washing, water waste, increase Unnecessary urban sewage investment and operating costs)
