A kind of recycled concrete preparation method

Abstract

The invention provides a method for preparing recycled concrete. The preparation and regeneration of concrete is completed by the cooperation of the installation frame group, the dust removal device, the spreading device, the sieving device and the material guide cover; The dust mixed in the concrete blocks is difficult to clean, which seriously affects the cohesiveness of the concrete blocks; and the size of the concrete blocks is different, and the current screening method is difficult to process the concrete blocks of different sizes, which makes it difficult to screen a large number of concrete blocks at the same time. Guarantee its screening effect and other problems.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a method for preparing recycled concrete. Background technique [0002] Recycled concrete means that waste concrete blocks are crushed, cleaned and graded, mixed with gradation in a certain proportion, partially or completely replaced by natural aggregates (mainly coarse aggregates) such as sand and gravel, and then added with cement, water, etc. new concrete. Recycled concrete can have the following situations according to the combination of aggregates: all aggregates are recycled aggregates; coarse aggregates are recycled aggregates, fine aggregates are natural sand; coarse aggregates are natural gravel or pebbles, fine aggregates The raw materials are recycled aggregates; recycled aggregates replace part of the coarse or fine aggregates. [0003] During the processing of recycled concrete blocks, the dust in the concrete blocks needs to be dedusted to ensure...

Problems solved by technology

[0003] During the processing of recycled concrete blocks, the dust in the concrete blocks needs to be dedusted to ensure the quality of the recycled concrete blocks. However, the dust mixed in the concrete blocks is difficult to clean during the recycling process of the current concrete blocks. , which seriously affects the cohesion of the concrete blocks; and the size of the concrete blocks is different, the current screening method is difficult to process the concrete blocks of different sizes, resulting in a large number of concrete blocks screening at the same time is difficult to ensure the screening effect
