Binding of walls made of aerated concrete. For the construction of walls, cellular concrete blocks and tiles produced in varieties are used 400, 500, 600, 700 and the following types:
a) blocks 49/36, 49/30, 49/24, 49/18, 59/36, 59/30, 59/24, 59/18 cm,
b) tiles 49/12, 49/6, 59/12, 59/6 cm.
Variety blocks and tiles 400 i 500 is used to insulate buildings and to make non-load-bearing walls, other varieties with a class greater than 3 < execution of walls of load-bearing walls.
Walls made of blocks and tiles are made in compliance with the binding rules applicable to the construction of brick walls, using the common binding rules. In thick walls 24 cm, lift type pulleys are used. and in walls with a thickness 37 cm blocks and tiles of the variety 07. Horizontal joints: must not exceed the thickness 15 mm, and vertical 10 mm.
Aerated concrete blocks and tiles cannot be used for the erection of walls with smoke or ventilation ducts. Such walls should be made of solid ceramic bricks. The walls in the basement and the lower part of the outer walls of the ground floor below should not be made of cellular concrete 0,5 m above the ground. In addition, it should not be used in rooms with high humidity (laundries).
Aerated concrete is brittle, therefore, heavy tools cannot be used to make holes in the walls. All cutouts and grooves should be made with saws (mechanical) or drills. The bonding of walls made of aerated concrete blocks and tiles is shown in the figure.
YTONG and HEBEL autoclaved aerated concrete blocks are widely used alongside SIPOREX blocks. YTONG blocks have a high dimensional accuracy and can be used to make walls with thin joints. When using a special masonry mortar, the joint thickness is less than 1 mm and not greater than 3 mm.
Walls made of thin-jointed blocks can be used as load-bearing and stiffening structural walls that transfer vertical loads from the ceilings of the upper floors, as well as horizontal from the wind.
Several varieties of YTONG blocks for masonry are produced,from which buildings with a height of two storeys can be made.
Walls made of YTONG blocks are made in compliance with the binding rules applicable to the construction of POROTHERM ceramic hollow brick walls and cellular concrete blocks using the principle of common bonding. The figure shows the connection of mutually perpendicular walls.
