Operation Steps:1.Clean the surface of the mold, and brush a layer of edible oil or release agent on the surface of the mold to facilitate demolding. Pay attention not to brush too much to prevent a large number of pores on the surface of the formed brick.2.Pour in the mixed cement mortar, cover the bottom of the mold about 1 cm high, grasp the edges of the mold around the edge of the multi-angle non-stop shaking, make the air in the cement mortar fully overflow, and then fill the remaining mold space.3.Place the mold filled with cement mortar horizontally and cover it with a film to prevent cracks on the surface of the brick due to the rapid evaporation of water. After the brick is fully condensed, take it out carefully.4.On the site where construction is needed, dig about 1 cm from the ground surface shallowly, put in the formed bricks, backfill the gaps around the bricks and compact them.
