Description

Lightweight cement board

This creation is about a light-weight cement board, especially a high-pressure steam-cured light-weight cement board stacked in a dry method.

When the traditional red brick wall is stacked, the area where the brick wall needs to be set is planned first. The red brick is fixed with an adhesive and arranged in layers in an intersecting manner. After stacking to an appropriate height, the cement and Dry sand smoothes the original uneven wall surface and then coats it with a thin layer of cement to lighten it for subsequent painting or laying of tiles.

However, although the above-mentioned red brick wall is strong but bulky, and the red brick wall must be constructed by wet method to make the red brick wall stronger, the biggest difference between the dry method and the wet method Before the wet construction method is used for stacking, the bricks must be soaked in water for one day, so that the pores in the bricks are filled with water, so that the water in the adhesive will not be absorbed by the bricks, and the wall will become unstable And it cannot be tightly combined, and the red brick has uneven surface after it is laid, so it needs to be finished and grounded. This method and procedure is not only to increase the weight of the wall and the working hours, but also The reason why the red brick wall needs more space for stacking, and the larger the area occupied by the wall, it also relatively reduces the space used by the occupants.
