Abstract

The invention discloses a waste concrete recycling process which comprises the following steps: (a) putting waste concrete into a collecting bin, separating plastic and plant impurities in the waste concrete through an air screening machine, and discharging the waste concrete; (b) injecting tap water into a clean water tank, putting the waste concrete in the step (a) into the clean water tank, soaking the waste concrete with the tap water, and cleaning the waste concrete; and (c) putting the waste concrete cleaned in the step (b) into a crusher, and crushing the large waste concrete. Plastic and plant impurities in the waste concrete are separated through the air screening machine, the waste concrete is subjected to primary treatment, the waste concrete is cleaned through clear water, and soil on the surface of the waste concrete is removed, so that the impurities of the waste concrete are separated out, the waste concrete is conveniently recycled, and the waste concrete recycling efficiency is improved. And the recycling rate of the waste concrete is improved.

Description

technical field [0001] The invention relates to the technical field of waste concrete recycling, in particular to a waste concrete recycling process. Background technique [0002] Concrete refers to the man-made concrete made of cement as the main cementitious material, mixed with water, sand and stones, and chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, uniformly stirred, compacted and cured. Stone and concrete are mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. Waste concrete refers to discarded concrete blocks. High-quality crushed and screened concrete blocks and silt can be used as concrete regeneration. Waste concrete blocks are not only high-quality concrete aggregates, but there are many advantages in using waste concrete blocks as aggregates. Concrete, cement an...
