A cement board is a combination of cement and reinforcing fibers formed into sheets, of varying thickness that are typically used as a tile backing board. [1] Cement board can be nailed or screwed to wood or steel studs to create a substrate for vertical tile and attached horizontally to plywood for tile floors, kitchen counters and backsplashes.
Magnesia cement board for building construction is available is various sizes and thickness. It is not a paper-faced material. It generally comes in light gray, white or beige. Grades include smooth face, rough texture, utility and versatile, and there are different densities and strengths for different applications and uses.
The Homasote base reduces the incidence of impact injuries such as shin splints caused by dancing on the concrete floor. Homasote is used in theatrical sets as a noise deadening layer for stage platforms consisting of a 3 ⁄ 4 -inch (19 mm) plywood sublayer, a 1 ⁄ 2 -inch (13 mm) Homasote layer, and a 1 ⁄ 4 -inch (6 mm) Masonite top layer.
Sheet sizes vary slightly from manufacturer to manufacturer but generally they range between 2400 – 3000 mm in length and 900 –1200mm in width (600 & 450 mm increments). This manufactured size minimizes on-site wastage as residential floor, wall and roof structures lay structural members at 450 or 600mm centres.
A standard metric (concrete) block is 190 mm wide, 390 mm long, and 190 mm high, which allows for 10 mm mortar joints in between bricks, giving a standard unit size of 200 mm square by 400 mm long. [3] A standard metric brick is 90 by 57 by 190 mm; with 10 mm of mortar, that produces a standard unit of 100 mm x 200 mm. [3]
Cork cement composites have several advantages over standard concrete, such as lower thermal conductivities, lower densities and good energy absorption characteristics. These composites can be made of density from 400 to 1500 kg/m 3, compressive strength from 1 to 26 MPa, and flexural strength from 0.5 to 4.0 MPa. [citation needed]
