Description

Technical Field

[0001] The invention relates to the technical field of concrete mixing and preparation, and in particular to a recycled fine aggregate ultra-high performance concrete and a use method thereof. Background Art

[0002] Recycled fine aggregate is processed from concrete, mortar, stone, bricks and tiles in construction waste. It is used to prepare concrete and mortar with a particle size of no more than 4.75 mm. In engineering construction, mixing equipment is often used to mix recycled fine aggregate with cement, sand and water to mix concrete and put it into use.

[0003] Publication No.: CN221540235U discloses a concrete mixing device, comprising: a mixing tank, a feeding port is arranged on the mixing tank, a slide rail is fixedly connected to the side surface of the mixing tank, a large gear is fixedly connected to the side surface of the mixing tank, a small gear is rotatably connected to the side surface of the large gear, the small gear is rotatably connected to a support plate through a rotating shaft, a motor A is fixedly connected to the rear surface of the support plate, a stabilizing frame is fixedly connected to the lower surface of the support plate, a connecting ring, the connecting ring is rotatably connected to a discharge box through a rotating shaft, a motor B is fixedly connected to the front surface of the discharge box, a driving shaft is fixedly connected to the output end of the motor B, and the A auger is fixedly connected to the side surface of the driving shaft, a support seat is fixedly connected to the upper surface of the stabilizing frame, and the support seat is located behind the support plate. The device is beneficial for avoiding the phenomenon that raw materials fall when entering directly from the feeding port due to a small feeding port, thereby improving the efficiency of mixing production. However, in actual use, the device and the existing equipment usually require a longer mixing time when mixing concrete with recycled fine aggregate. The long mixing time of concrete will cause the aggregate to absorb more water, reduce the free water content in the clinker, cause the loss of slump, and thus affect the subsequent molding quality. The mixing quality of concrete produced by existing equipment using recycled fine aggregate has further room for improvement. Summary of the invention
