During the construction process of air-entrained blocks, certain specifications and standards must be paid attention to. Construction details must have certain requirements. Concrete air-entrained blocks are widely used in various construction industries. In order to prevent concrete from cracking during the construction process, the following contents must be paid attention to
Construction process Materials of different materials are often required. The most common ones are concrete air-entrained blocks and steel bars. During use, steel bars often form some filling materials. Such lightweight concrete air-entrained blocks and reinforced concrete air-entrained blocks are made of different materials due to differences in physical properties. Cracks in the wall are inevitable, but they can be reduced to a minimum if materials are selected during construction.
When stacking fly ash concrete air-entrained blocks, the thickness of the ash joints should be minimized and no less than a gap should be left at the bottom of the beam slab. Filling of the gaps should be done after the masonry is completed. The filling material should be densely filled with fine stone concrete mortar that has a larger shrinkage than concrete, or side bricks or vertical bricks should be used for diagonal top tightness.
During the manufacturing process of air-entrained blocks, air-entrained blocks are prone to cracks due to internal tension and external pressure. These cracks belong to the air-entrained blocks themselves and are often proven to be substandard products. They may also be used in the use of concrete air-entrained blocks. There were no cracks when it was poured, but when it was poured with water, it shrank and cracks occurred. It is shown that during construction, the moisture content of the concrete air-entrained blocks should be controlled as follows. Before the air-entrained blocks are laid, the masonry surface should be watered and moistened to reach a saturated surface dry state.
During the construction process, the faster is not the better. Especially the daily workload of the air-entrained block construction must be controlled. The height of the daily masonry should be controlled. The overlapping size of the air-entrained blocks should be controlled according to standards. Damaged air-entrained blocks must not be used. Blocks must not be cut with tile knives, etc. Air-entrained blocks should be cut with special tools. Concrete air-entrained blocks of the same batch number should be used to build the same wall. When the length of the air-entrained block wall is greater than 100 meters, structural columns should be added. When the height of the tie bars is greater than the height of the tie bars, ring beams should be added. Steel mesh should be added to the joints between the wall and beams, slabs and columns.
