Abstract

The invention provides a preparation method of high-performance dry-mixed mortar, which comprises the following steps: providing machine-made sand, and drying; conveying the dried machine-made sand toa probability sieve using a belt conveyor and an elevator, sieving the machine-made sand into coarse, medium and fine sand with different specifications, and storing the sand; selecting sand of different specifications according to different requirements for manufacturing mortar; by weight, feeding 100 to 130 parts of PO42.5 cement, 70-90 parts of stone powder, 800-820 parts of sand and 0.4-0.6 part of an admixture into a stirrer to be mixed and stirred for longer than 3 minutes; and after stirring, conveying obtained mortar into a special mortar tank on a construction site through a transport vehicle to be continuously stirred for later use. The beneficial effects are that: the mortar can be used while being mixed, the quality is reliable, the construction performance is improved, the characteristics of water retention, modification and consistency of the admixture are fully utilized, the workability and operability of mortar are improved, and the working and production efficiency ofconstructors is improved.
