Construction sequence

       Cladding layer pouring → Bottom layer pouring → Placement of nozzle block → Breathable brick bottom aluminum-magnesium-carbon brick masonry → fill gap with corundum cement → magnesium carbon brick wholesale clad aluminum magnesium carbon brick masonry clad slag line Carbon brick masonry → Baokou aluminum and magnesium castable masonry → curing → baking.

       Masonry construction of clad aluminum-magnesium-carbon brick

       ① Use aluminum-magnesium fire mud for wet masonry. The masonry mud must not be too thin. The mud between brick joints must be full, and the brick joint must be less than 1mm.

       ② Each layer of brickwork is flat, and the brick gaps between layers must be staggered. In masonry, the principles of "back-to-back, tight seams, and arcs" shall be followed, and the joints between the upper and lower layers shall be staggered.

       ③ Cut the size of the closing door brick to be not less than 50mm, and avoid the position of the trunnion. The door-to-door position between the layers is staggered by more than 200mm.

       Bottom building construction technology

       ① Ventilation bricks and nozzle blocks must be placed flat and correctly positioned.

       ② The gap between the nozzle block and the ventilated brick and the surrounding brick-laying bricks are filled with corundum cement.

       Construction requirements

       ① Check the construction equipment (mixer, water supply, vibration rod, etc.);

       ② Turn on the mixer, add the mixture, dry mix for 1 minute, add 2/3 of water, then slowly add the remaining water, wet mix for 3 ~ 5 minutes to discharge;

       ③ Vibrate with a vibrating rod after each pouring of the milling material, and fully discharge the pouring material.

       ④ It is necessary to maintain continuity before and after the pouring construction, and the material stopping time during the process shall not exceed 20 minutes.

       Construction requirements for underfloor excavation

       ①Remove the cement blocks and the surrounding cement and clean them up;

       ② Hang the new ventilated brick and seat brick into the placement position;

       ③ Use corundum cement to fill the gaps between ventilated bricks, nozzle blocks and aluminum-magnesium-carbon bricks.
