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.
Magnesium oxide wallboard (10 mm thickness) Magnesium oxide, more commonly called magnesia, is a mineral that when used as part of a cement mixture and cast into thin cement panels under proper curing procedures and practices can be used in residential and commercial building construction.
Transite originated as a brand that Johns Manville, an American company, created in 1929 for a line of asbestos-cement products, including boards and pipes. [1] In time it became a generic term for other companies' similar asbestos-cement products, and later an even more generic term for a hard, fireproof composite material , fibre cement ...
Lignocellulosic fibers in a cement matrix can degrade due to the hydrolysis of lignin and hemicelluloses. [12] [13] The amount of fibers added to a concrete mix is expressed as a percentage of the total volume of the composite (concrete and fibers), termed "volume fraction" (V f). V f typically ranges from 0.1 to 3%. The aspect ratio (l/d) is ...
GRC (Glass fibre-reinforced concrete) ceramic consists of high-strength, alkali-resistant glass fibre embedded in a concrete & ceramic matrix. [1] In this form, both fibres and matrix retain their physical and chemical identities, while offering a synergistic combination of properties that cannot be achieved with either of the components acting alone.
To give a conservative estimate and build redundancies into the final structural system, the ACI Building Code Requirements give a maximum reduced design load of where is the strength reduction factor for the type of column used.
Roof sheeting, known as Hardies "Super Six" Roofs - most usually on industrial or farmyard buildings and domestic garages. Flat sheets for house walls and ceilings were usually 6 and 4.5 mm (0.24 and 0.18 in) thick, 900 and 1,200 mm (35 and 47 in) wide, and from 1,800 to 3,000 mm (71 to 118 in) long.
Geopolymer cement is an alternative to ordinary Portland cement and is used to produce Geopolymer concrete by adding regular aggregates to a geopolymer cement slurry. It is made from inorganic aluminosilicate (Al-Si) polymer compounds that can utilise recycled industrial waste (e.g. fly ash , blast furnace slag ) as the manufacturing inputs ...
