And the internal stress caused by the formation of the block; and the block of the invention has no gray mouth, the composition of the mortar powder is consistent with the block aggregate, and the block is demoulded at the same time because some parts are not slightly deformed by the joint body. The internal stress of the forming is eliminated, so that the above two types of cracks are not formed after the block wall of the present invention.
- the 390x 190x190 block has too much tolerance during the processing. Therefore, the two sides must be sanded and ashed after the masonry. The amount of this project accounts for about 10% of the total cost, 30% of the construction period, and 30% of the labor. %. However, the machining tolerance of the block of the present invention is ⁇ 0.20 mm. If the work is done according to the operation rules, the two-side plastering work can be canceled and directly transferred to the decoration.
