[0043] The present invention will be described in detail below in conjunction with the accompanying drawings. As shown in the accompanying drawings:
[0044] A preparation method of recycled aggregate ready-mixed mortar:
[0045] (1) Preparation of recycled aggregate: Use waste concrete, waste bricks, and waste sand and ash construction waste less than 690mm in size as raw materials, determine the quantity according to needs, and carry out grade screening after crushing and drying with a moisture content of less than or equal to 0.5%. In the grade screening process, magnets are used to remove metals, and wood chips, plastics and sundries are removed in the manner of specific gravity, so that the particles are prepared into 0.075-0.15mm, 0.15-0.3mm, 0.3-0.6mm, 0.6-1.18mm , 1.18-2.36mm, 2.36-4.75mm, 4.75-10mm, 10-32mm recycled aggregates, the recycled aggregates are stored separately according to the particle size for use;
[0046] (2) Preparation of cement type 32.5 masonry m...
