A kind of preparation method of high-strength green recycled concrete

Abstract

The invention relates to a method for preparing high-strength green recycled concrete, and relates to the technical field of municipal building construction. It uses a high-strength green recycled concrete cleaning device, and the device includes a vibrating device, and the vibrating device performs recovery and regeneration on the recycled concrete. Vibrate to remove the miscellaneous materials on the concrete surface, and also include a cleaning device, which is used to remove the miscellaneous dust attached to the concrete surface. plate, the second conveyor belt, slag blower and electromagnetic vibrator, and the cleaning device includes a fixed plate, a rotating roller, a driving roller, a driving gauze, a driving motor, a water spray head and a water collecting tank; It has the effect of low work intensity and high work efficiency when cleaning up miscellaneous objects.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a preparation method of high-strength green recycled concrete. Background technique [0002] Concrete, referred to as "concrete" for short, refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. [0003] In the process of concrete production, certain concrete slag and concrete waste will be produced, and the concrete slag and concrete waste will often be discarded. The discarded concrete slag and concrete waste ...

Problems solved by technology

[0003] In the process of concrete production, certain concrete slag and concrete waste will be produced, and the concrete slag and concrete waste will often be discarded. The discarded concrete slag and concrete waste will have an impact on the environment during actual use. Now Some enterprises tend to recycle high-strength building materials that can be reused in concrete waste, such as some stones, steel bars, etc. can be recycled again; but when these stones, steel bars, etc. are used directly, the stones There will be dust, plastic, foam and other impurities attached to the steel bars, which will affect the use of stones and impurities and reduce the strength of stones and cement after solidification. Therefore, it is particularly important to clean up impurities in high-strength recycled recycled concrete. When cleaning the impurities on the concrete surface, it is often cleaned by manual picking, which has high work intensity and low operation efficiency, so there is still room for improvement
