Abstract

The invention provides an evaluation and detection method of construction waste recycled coarse aggregates. The evaluation and detection method comprises the following steps: S1, obtaining i test construction waste recycled coarse aggregates, wherein i is greater than or equal to 5, and the proportions of the bricks in each part of the test construction waste recycled coarse aggregate are different; S2, detecting a P value, a wx value and a Qa value of each part of the test construction waste recycled coarse aggregate; S3, fitting the P value, the wx value and the Qa value in the S2 according to a formula P=a*wxb*Qac to obtain parameters a, b and c; and S4, detecting the water absorption rate wx and the crushing value Qa of the to-be-evaluated construction waste recycled coarse aggregate, and then obtaining the total content P of bricks and mortar of the to-be-evaluated construction waste recycled coarse aggregate according to the parameters a, b and c obtained in the S3 and the formula P=a*wxb*Qac. According to the evaluation and detection method provided by the invention, the limitation of a visual inspection manual sorting method is overcome, and the brick and mortar contents in different batches of recycled coarse aggregates can be conveniently and reliably obtained.

Description

technical field [0001] The invention relates to a quantitative detection method, in particular to a method for evaluating, detecting and classifying regenerated coarse aggregate of construction waste. Background technique [0002] Recycled coarse aggregate of construction waste refers to particles processed from waste concrete, bricks, mortar, etc., with a particle size greater than 4.75mm. Due to the complex sources of construction waste, different batches of recycled aggregates of the same specification produced by the same manufacturer also have the problem of large differences in the components of waste concrete, bricks, and mortar. Moreover, the discrete quality of recycled coarse aggregates will affect performance. cause greater impact. [0003] The difference in the components of bricks and mortar in the recycled coarse aggregate of construction waste mainly has a significant impact on its water absorption and crushing value indicators. Mortar and bricks have a loos...
