Abstract

The invention relates to the technical field of concrete, in particular to a recycled concrete preparation method and equipment. The method comprises the following steps: crushing waste coagulable soil to form waste mud, adding straw ash into the waste mud, stirring to obtain primary recycled concrete, reducing the phenomenon that the concrete is prone to bleeding or segregation in the stirring and mixing process, adding hair into the primary recycled concrete, stirring to obtain secondary recycled concrete to increase the the toughness of the concrete; and finally, adding a waterproof agent into the secondary recycled concrete, stirring, cooling and forming to obtain the recycled concrete, and supplementing cracks. The durability of the recycled concrete is enhanced, the compressive strength of the recycled concrete is improved, and the recycled concrete is not easy to break after being formed. The problem that recycled concrete is prone to fracture is solved.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a method and equipment for preparing recycled concrete. Background technique [0002] Recycled concrete refers to the new concrete prepared by crushing, cleaning and grading waste concrete blocks, mixing them with gradation in a certain proportion, replacing part or all of natural aggregates such as sand and gravel, and then adding cement and water. [0003] The waste concrete is subjected to a large external force during the crushing process, which leads to a large number of fine cracks in the aggregate, which makes the recycled concrete easy to break. Contents of the invention [0004] The purpose of the present invention is to provide a method and equipment for preparing recycled concrete to solve the problem that recycled concrete is easy to break. [0005] To achieve the above object, the invention provides a method for preparing recycled concrete, which specifically com...
