Civil engineering structures are of many types, such as road, buildings, bridge etc. The type of building material to use in a civil engineering structure is dependent upon many factors, such as it life time, purpose, loads it must carry, environmental condition it is exposed to etc. Therefore different types of brick are manufactured in order to suit a particular requirement.
Acid Resistant Bricks
Bricks used for masonry construction, such as flooring, subject to acid attack, lining of chambers and towers in chemical units, lining of sewers carrying industrial effluents, etc, to prevent deterioration of the surface by acids.
Common Building Solid Bricks
The burnt clay building bricks which are commonly used in building and civil engineering construction work in which frogs do not exceed 20 percent of this volume.
Bricks made specially for facing purpose, that is, which are being exposed in use.
Heavy Duty Bricks
Bricks required for masonry in heavy engineering work, such as, bridge structure, industrial foundations and multi-storeyed buildings having high durability and compressive strength and lower water absorption.
Bricks which are used as a paving material for roads, heavy duty industrial floors, particularly suited to resist heavy wear and tear from steel tyred traffic.
Bricks in which the holes passing through the bricks exceeds 25% of the volume and the holes are small. A small hole is a hole less than 20 mm wide and less than 500 mm2 in area. The hole may be circular, rectangular or square or any other regular shape.
Bricks intended to use in the lining of the walls, roofs and floors of sewers used for the ordinary sanitary sewage.
Bricks used for soling purpose. They are different from common building bricks.
