Abstract

The invention discloses a device for improving the active performance of aggregates used in recycled concrete processing, which comprises a pretreatment box, a modified treatment box and a support frame. It runs through the pretreatment box, and the first rotating shaft is engaged with the first gear and the second gear. The first gear is arranged on the first rotating shaft on the left side, and the second rotating shaft is arranged on the first rotating shaft on the right side. gear, the second stirring rod is rotatably connected to the top end of the after-treatment box, and the inner wall of the after-treatment box is provided with a partition, the after-treatment box is arranged behind the modified treatment box, and the treatment box is provided with a drying mechanism. In this device for improving the active performance of aggregates used in recycled concrete processing, part of the waste concrete after screening falls into the modification treatment box as recycled aggregates, which can improve the performance of the aggregates through the reaction of glacial acetic acid and cement hydrate in the recycled aggregates. The role of the surface of recycled aggregate particles, thereby improving the performance of recycled aggregates.

Description

technical field [0001] The invention relates to the technical field of recycled concrete processing, in particular to a device for improving the active performance of aggregates used in recycled concrete processing. Background technique [0002] Recycled concrete refers to the new concrete made by mixing waste concrete with cement, water, etc. after crushing and cleaning. Since the waste concrete after crushing is used as recycled aggregate, its performance is worse than that of natural aggregate. Many performances of the recycled concrete are adversely affected, and a device for improving the active performance of aggregates for recycled concrete processing is needed to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a device for improving the active performance of aggregates for processing recycled concrete, to solve the problem in the above-mentioned background technology that the performance of waste concr...
