Ceramic bricks

Brick Ceramic ordinary (ordinary), full-bodied - a rectangular parallelepiped of size 250x120x65 mm, at least - 288hh138hb5 (modular). For ceramic brick thickness of 88 mm and unit required the presence of round and slotted holes. Density 1600-1900 kg/m3 brick. Brick must be properly burned, as underburning (red brick) has insufficient strength, low water and frost. Bleach brick (iron ore) has a higher density and thermal conductivity, and are usually irregular in shape. To appoint a ceramic brick is facing, construction and special. Building bricks are designed to build internal and external walls. Facing brick outer surface has a high quality, resists water, frost and suitable for virtually all outdoor activities. Ceramic brick is specially designed for specific operating conditions. In frost resistance bricks is classified into four grades: P-15, -25, -35 and -50. Ordinary ceramic brick masonry is used for exterior and interior walls, making wall blocks and panels, masonry stoves and chimneys in places where the temperature does not exceed the temperature of firing bricks. Brick dry pressing is not recommended for laying the foundations and plinths below the waterproofing layer. Brick clay common inappropriate use of frame houses and walls of upper floors, since it has an excessive strength, weight and relatively high thermal conductivity. In such buildings is far more profitable to apply the "effective" brick with less weight. The strength of ceramic bricks. These qualities define the ability of the material to resist degradation caused by external forces that cause it the internal stresses. It is characterized by a tensile strength for three kinds of exposure to - compression, tension and bending. Brand ceramic bricks ascertain experiencing its compressive and flexural strength (kg/cm2). Ceramic brick is divided into grade 50, 75, 100, 125, 150, 175, 200, 250 and 300. For masonry low-rise brick buildings strength can be quite low (M100 - M150). Ceramic bricks lekalny. Production is similar to the usual radial brick, manufactured plastic way. Brick lekalny release length 80-225 mm. On strength indicators gauged brick is divided into three grades: M125, M100 and M50. Apply lekalny ceramic brick masonry industrial chimneys and lining of pipes in the cases of heating a brick flue gas to not more than 700 ° C. Property durability of ceramic brick refers to a comprehensive quality features and is expressed in the ability to resist the complex influence of external and internal factors that are manifested in the operational phase of construction ceramic bricks.
