Production process of concrete with quantitative function for preparing recycled aggregate concrete

Abstract

The invention discloses a production process of concrete with a quantitative function for preparing recycled aggregate concrete, and relates to the technical field of preparation of recycled aggregateconcrete. The production process specifically comprises the following steps of: S1, recycling waste concrete; S2, drying and preparing materials; S3, testing hardness; S4, obtaining recycled aggregate; and S5, preparing the recycled concrete. According to the production process of the concrete with the quantitative function for preparing the recycled aggregate concrete, grinding of coarse recycled aggregate and fine recycled aggregate can be completed at one time according to hardness characteristics of different parts of the waste concrete through a tested standard pressure value, so that the working efficiency is improved; the coarse recycled aggregate and the fine recycled aggregate are distinguished according to the hardness characteristics of different parts of the waste concrete, sothat the production process has the advantages that the hardness of the coarse recycled aggregate is sufficient, and the fine recycled aggregate is smoothly processed; and a feeding machine with thequantitative function is used for feeding, so that the proportion of each material is accurately controlled, and the quality of the recycled concrete is improved.

Description

technical field [0001] The invention relates to the technical field of preparation of recycled aggregate concrete, in particular to a concrete production process with quantitative function for the preparation of recycled aggregate concrete. Background technique [0002] With the development of our country's economy, it is often necessary to dismantle and rebuild small buildings in various regions, so a large amount of waste concrete will be produced. If it is not treated and landfilled, it will often cause surrounding environmental pollution and waste land and resources. With the development of the construction industry, people's demand for natural aggregates of sand and gravel is increasing day by day, and natural aggregates are non-renewable resources. Excessive exploitation will often bring about hazards such as resource depletion and landslides. Therefore, people recycle waste concrete to generate regeneration The research and development of aggregates has been paid more...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a concrete production process with quantitative functions for the preparation of recycled aggregate concrete, which solves the problem that the existing production process of recycled aggregate concrete proposed in the above background technology can only focus on coarse recycled bone According to the hardness characteristics of waste concrete, it is impossible to distinguish between coarse recycled aggregate and fine recycled aggregate, which will easily lead to insufficient hardness of the produced coarse recycled aggregate or fine recycled bone. The problem that the material cannot be processed due to its hardness during the production process
