Hydraulicity gelled material uniformly excited by taking multiple industrial solid wastes as raw materials

Abstract

The invention discloses a hydraulicity gelled material uniformly excited by taking multiple industrial solid wastes as raw materials. A finished product is prepared by uniformly mixing discharged solid waste materials such as blast furnace slag micro-powder and steel-slag micro-powder caused by production in iron and steel plants, solid waste materials such as flyash and desulphurization ash discharged by thermal power generation plants, discharged coal gangue micro-powder caused by production of coal mines and exciting agents which are prepared from cement clinker micro-powder and discharged waste materials caused by production in chemical plants in different proportions according to different properties and requirements on rocks and soil. The hydraulicity gelled material is used as a solidifying or hardening material of the rocks and soil; compared with conventional cement, the hydraulicity gelled material has the advantages that the strength of the prepared cemented body is obviously enhanced, and the compactibility of the cemented body is improved; moreover, the hydraulicity gelled material has relatively high impermeability resistance, cement can be completely and functionally replaced by the hydraulicity gelled material, and the hydraulicity gelled material is applied to reinforcement of a rock-soil body or formation of water-resisting curtains. The hydraulicity gelled material has the characteristics of greenness and environmental protection; the energy consumption of a material processing process is extremely low, the pollution to environment is avoided, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a hydraulic gelling material that uses industrial solid waste as a raw material and homogeneously excites it according to the application ratio. Background technique [0002] In soft soil foundation reinforcement, temporary enclosure structures and water-stop curtains for deep foundation pits, embankments of water conservancy projects, etc., construction methods such as mixing piles, rotary grouting piles and high-pressure grouting are commonly used to combine ordinary cement with soil Stir and mix to form a reinforced body with a certain strength to improve the bearing capacity of the foundation and the performance of retaining soil and water. Lime or cement is often used as a solidification material in the dredging works of the base and sub-base of road engineering and river bank tidal flats to improve the bearing capacity of the foundation. However, the strength of...

Problems solved by technology

Through years of research and development, a series of building material products have come out, but these used solid wastes are estimated to only account for 20% of the total waste, and the remaining waste will bring great harm to the environment and society. At the same time, some useful resources in these wastes cannot be rationally utilized, resulting in a great waste of resources.
