Abstract

The invention discloses a building aggregate regeneration device and a use method thereof, and relates to the technical field of concrete recycled aggregates. The problem that recycled concrete aggregates are poor in strength is solved. The building aggregate regeneration device comprises a top plate and a supporting base, wherein the outer wall of the bottom end of the top plate is connected with an electric push rod through a bolt. A working method of the building aggregate regeneration device comprises the following steps: guiding Portland cement, silica fume, quartz powder, fine aggregates and smashed concrete into a blending hole; and introducing water containing a water reducing agent into a water storage chamber, and putting steel fibers into a fiber storage ring. By arranging an electric push rod, a stirring plate and a circular hole, a rotating rod rotates to drive a stirring connecting rod to rotate, the stirring plate rotationally connected with the stirring connecting rod also starts to rotate around the rotating rod, and meanwhile, the stirring plate also starts to rotate in a material, so that the blended material and the crushed waste concrete are fully stirred, and the quality of the recycled concrete aggregates after production is improved.

Description

technical field [0001] The invention relates to the technical field of concrete recycled aggregate, in particular to a building aggregate recycling device and a method for using the same. Background technique [0002] Aggregate prepared from waste concrete is called recycled concrete aggregate. At present, in the prior art, the recycled aggregate particles prepared by simple crushing and screening process have many edges and corners, rough surface, and hardened cement mortar in the components. In addition, during the crushing process of the concrete block, a large number of micro-cracks are caused by the accumulation of damage inside, which leads to the large porosity, high water absorption rate, small packing density, large porosity, and high crushing index of the recycled aggregate itself. Therefore, it is urgently needed A building aggregate recycling device and a method for using the same. [0003] After searching, the Chinese patent application number is CN201510046097...
