Problems solved by technology

However, in the current grading ratio of construction solid waste recycled road water stabilization layer, the amount of fine aggregate below 9.5mm is less than 50%, and more than 20% of the fine aggregate cannot be fully utilized
Therefore, if these fine materials cannot be fully and rationally utilized, it will result in a waste of construction solid waste renewable resources, and at the same time bring new environmental pollution problems, and the treatment cost will remain high

Abstract

The invention discloses a cement-stabilizing layer material of regenerated fiber-reinforced building solid waste recycled fine aggregate and a preparation method of the cement-stabilizing layer material. Building solid waste recycled fine aggregate and Portland cement serve as main materials and are doped with regenerated fibers and water, stirring and blending are carried out, and the cement-stabilizing layer material is obtained. The added fiber material and the cement material act synergistically, and thus the building solid waste recycled fine aggregate can be stably aggregated to form an integral structure. The added fiber material has high tensile strength and forms a network skeleton structure in the mixture, the toughness and impact resistance of the cement-stabilizing layer material can be obviously improved, generation and development of cracks can be effectively prevented, and the anti-scouring property, the freezing resistance and other endurance properties of the cement-stabilizing layer can be improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of water-stabilizing layer materials for road bases, and in particular relates to a water-stabilizing layer material for regenerated fiber-reinforced construction solid waste recycled fine aggregate and a preparation method thereof. Background technique [0002] In the past ten years, with the acceleration of urbanization and industrialization in my country, urban construction has progressed from extensive development and large-scale old city renovation, to large-scale construction of residential quarters and reconstruction and expansion of roads, resulting in the rapid generation of a large amount of construction waste. At present, domestic construction waste treatment basically remains in the backward and simple landfill treatment. Due to the non-degradability of construction waste, landfill treatment will bring disastrous consequences to the society. The simple processing method consumes a ...
