Brick #1: 76.32% SiO 2, 21.96%Al 2 O 3, 1.88%Fe 2 O 3 traces of CaO and MgO, commercial brick, density 1.795 g ⋅ cm −3. Brick #2: 76.52%SiO 2, 13.67%Al 2 O 3, 6.77%Fe 2 O 3, 1.77%CaO, 0.42%MgO, 0.27%MnO, no specified density. Judging from the descriptions the TPRC has put the wrong labels on their bricks, and if that is the case then Brick ...
Bricks of dimensions 215 mm × 102.5 mm × 65 mm; Mortar beds (horizontal) and perpends (vertical) of a uniform 10 mm. In this case the co-ordinating metric works because the length of a single brick (215 mm) is equal to the total of the width of a brick (102.5 mm) plus a perpend (10 mm) plus the width of a second brick (102.5 mm).
They differ between full clinker (KMz) with a density of 2.0 to 2.2 kg/dm 3 (120 to 140 lb/cu ft) and high hole clinker (KHLz) with a density of 1.6 to 1.8 kg/dm 3 (100 to 112 lb/cu ft). Because of their low porosity, clinker bricks are inferior thermal insulators, compared to normal bricks.
the medium gross density of 850 kg/m 3 to 1.100 kg/m 3 (white coloured blocks, suitable for standard usage) the high gross density blocks of 1.100 kg/m 3 to 1.500 kg/m 3 (reddish colour, suitable for walls with higher acoustic performance requirements) The dimensions of these blocks are: length 500 mm, height 500 mm. Four blocks thus make 1 m 2.
In the making of firebrick, fire clay is fired in the kiln until it is partly vitrified.For special purposes, the brick may also be glazed. There are two standard sizes of fire brick: 9 in × 4 + 1 ⁄ 2 in × 3 in (229 mm × 114 mm × 76 mm) and 9 in × 4 + 1 ⁄ 2 in × 2 + 1 ⁄ 2 in (229 mm × 114 mm × 64 mm). [2]
Stronger and less porous engineering bricks (UK Class A) are usually blue due to the higher firing temperature [3] whilst class B bricks are usually red. Class A bricks have a strength of 125 N/mm 2 (18,100 lb f /sq in) and water absorption of less than 4.5%; Class B bricks have a strength greater than 75 N/mm 2 (10,900 lb f /sq in) and water ...
Standards for foundations are similar to those for brick walls. A CEB wall is heavy. Footings must be at least 10 inches thick, with a minimum width that is 33 percent greater than the wall width. If a stem wall is used, it should extend to an elevation not less than eight inches (200 mm) above the exterior finish grade.
