Suggestions for cutting expansion joints in epoxy flooring

(1) The construction process is basically the same as item A.

(2) The concrete mix proportion should use fine aggregate concrete with smaller particle size (less than 1/2).

(3) In order to ensure the complete bonding between new and old concrete, the old concrete surface should be cleaned of all foreign objects, floating slag, and impurities, kept clean, coated with interface adhesive or roughened, or sprayed with pure cement slurry before pouring.
