A kind of preparation method of energy-saving green high-strength concrete

Abstract

The invention relates to an energy-saving green high-strength concrete preparation method, which uses an energy-saving green high-strength concrete preparation device, the energy-saving green high-strength concrete preparation device comprises a crushing mechanism, a screening mechanism and a mixing mechanism, and the present invention adopts a multi-stage treatment The designed pulverizing mechanism realizes the pulverization of waste residue through the back and forth grinding motion, and the pulverization effect of different sizes of waste slag is improved by changing the grinding distance, thereby improving the overall pulverization effect of the waste slag. , the set screening and feeding mechanism can realize the screening treatment of slag and cut off the dust generated by screening, and the movable connection method adopted by the stirring structure in the mixing mechanism can facilitate the smooth progress of disassembly and cleaning, thereby avoiding this problem. The surface of the structure forms a thicker concrete adhesion crust, which affects the effect of mixing and stirring.

Description

technical field [0001] The invention relates to the field of concrete processing, in particular to an energy-saving green high-strength concrete preparation method. Background technique [0002] 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, also known as ordinary concrete, green, high-light High-strength concrete refers to concrete materials that can not only reduce the load on the earth's environment, but also coexist harmoniously with the natural ecosystem, and create a comfortable environment for human beings. Green high-strength concrete has better mechanical properties and durability than ordinary concrete, and its extensive use Industrial waste (cinder, coal stone, etc.) or construction waste (waste concrete, waste bricks, waste mortar, etc.) and other resources, the waste or waste slag is crushe...

AI Technical Summary

Problems solved by technology

[0003] 1. The degree of crushing of waste residues of different sizes is not uniform and the crushing treatment is relatively simple, so that the overall crushing effect of waste residues is low, and the screening degree of crushed residues is low, so that the residues cannot be fully utilized effectively , but also affect the quality of concrete preparation;

[0004] 2. When the waste residue is only subjected to a single crushing process, the overall crushing fineness is low. During the mixing process of the crushed slag and basic raw materials, the surface of the mixing structure is more likely to accumulate more concrete, and it is easier to Form an adhesive scab layer, and the existence of the adhesive scab layer will affect the subsequent stirring effect
