Problems solved by technology

At present, many roadbeds in foreign countries use inorganic binders to stabilize the roadbed, but on the one hand, some materials have no hydraulicity or low hydraulicity, which cannot really improve the stability of the roadbed; on the other hand, inorganic binders using natural aggregates, It will greatly increase the cost of road construction

Abstract

The present invention relates to a kind of inorganic regenerated concrete mixture and its preparation process. The inorganic regenerated concrete mixture is prepared with waste concrete regenerated aggregate and industrial waste slag as main material and through adding activating agent and water and through stirring. The mixture has the features of high strength, good hydraulicity and powerful deformation resistance. It is one ideal road base material and may be used widely in the road construction in soft soil foundation area.

Description

technical field [0001] The invention belongs to the technical field of road engineering base materials, and in particular relates to a novel mixture synthesized from recycled concrete aggregates and industrial waste residues as main raw materials and a preparation method thereof. Background technique [0002] In most areas of our country, the geological conditions are mostly typical wet soft soil or clay, and its biggest feature is poor water stability. High compressibility and easy deformation. If these soft soils or clays are used as road bases or cushions, the clay will cause a series of diseases in the roadbed under the action of its own weight stress and dynamic load, forming uneven settlement or roadbed consolidation deformation, and causing roadbeds or roads to appear. Stress concentration areas or accumulation of deformation will cause road surface cracking, displacement, unevenness and bridge head jumping, which will greatly affect the service life of the road and ...
