Bricks
Bricks are the mainstay in construction, and they are used by stacking the bricks in a special system according to the design and attaching them to each other with a brick adhesive called cement, which is very well known. before stacking.
There are things that must be checked before using the bricks, namely: the bricks are free of coal and clay, are uniform in color, the dimensions are regular, ensure that they are not water-absorbent, that they have passed the strength test, that they are free of cavities and decay, and finally that they are dry.
Advantages of using bricks
Regular shape of building facades as a result of regular size of bricks used in construction, length, width and height.
Ease of use in construction and transportation to the construction site due to its small size and weight.
Easy adhesion is cement.
Good fire resistance, unlike the wood used in building sheds, because it was previously burned during the manufacturing process.
Resistant to external factors such as rain, wind, sounds, etc.
concrete brick s
Solid municipal brick: It is a brick that does not contain internal voids, except for two circular holes, each with a diameter of 10 cm. However, its use has been reduced due to its high cost, heavy weight, and prolonged moisture retention. It is also difficult to conduct sanitary and electrical installations through it.
Hollow bricks: are bricks that contain artificial openings or voids. It has two types of hollow light bricks, and its weight is very light due to the large voids in it, and therefore it is used only for special cases due to its high price.
As for the other type, it is the regular hollow brick, and it is divided into several sections according to the dimensions of its size, and this brick is called according to the length, which is the T dimension.
pumice brick itung
It is considered a lightweight brick compared to the rest of the types, and it is a good heat and sound insulator, and its efficiency in that is equivalent to 6 times that of concrete stone, and its surface needs to be treated after applying a layer of plaster. It is used in the construction of walls and ceilings, and it is very expensive.
Ribbed roof brick: It is a kind of ordinary hollow brick, and it is manufactured in different dimensions according to the use.
Silicate refractory bricks
Most of it is imported from Italy, and its main component is silica sand, and its color is white, and the materials used in its manufacture are the same materials that are used in the manufacture of ordinary hollow bricks, but it is not hollow at all, and its uses include building arches and decorations because of their durability.
glass bricks
They are made of glass, have different shapes, and are either transparent or patterned. It also has different dimensions and one of its uses is building mortar of white cement and quartz, and it is also used to create iron skewers for construction because it is durable and rust-resistant.
Sand-lime brick
Lime: Quick or slaked lime must be in accordance with American specifications and standards.
Sand: The sand used should be of a siliceous type, free of salts and organic impurities, and of good classification.
Water: Fresh water is suitable for drinking for building purposes due to the lack or absence of impurities in it.
