BAIJIAN - Third party testing organization
Brick is the most traditional masonry material. The development has gradually shifted from clay as the main raw material to the utilization of industrial waste such as coal gangue and fly ash、 and from solid to porous and hollow、 and from sintered to non sintered
Testing items
Sodium oxide、 magnesium oxide、 aluminum trioxide、 silicon dioxide、 phosphorus pentoxide、 sulfur trioxide、 potassium oxide、 calcium oxide、 titanium oxide、 vanadium pentoxide、 manganese oxide、 iron oxide、 nickel oxide、 zinc oxide、 calcium carbonate、 and heat treated aerated concrete.
Measurement of moisture content in polymer concrete and artificial stone blocks. Determination of water absorption of clay block moisture-proof layer through water boiling、 determination of freeze-thaw resistance of calcium silicate blockBrick classification
1. Classification by material: clay brick、 shale brick、 coal gangue brick、 fly ash brick、 lime sand brick、 concrete brick、 etc
2. Classified by porosity: solid bricks (bricks with no pores or less than 25% pores)、 porous bricks (bricks with porosity equal to or greater than 25% and small but numerous pores、 commonly used in load-bearing areas with higher strength levels)
3. Hollow bricks (bricks with porosity equal to or greater than 40% and large but few pores、 commonly used in non load-bearing areas with lower strength levels)
4. Classified by production process: sintered bricks (bricks made by roasting) Steam pressed bricks、 steam cured bricks
