The most common type of cement is Portland cement, which is the basic ingredient of concrete and mortar. It is made of Portland cement clinker (calcium silicates, aluminium and other compounds) and other minor constituents. Portland cement clinker is produced by heating a mixture of raw materials up to 1450° C in a kiln. There are three production stages: preparation of the raw mixture, production of the clinker, preparation of the concrete. Limestone is the main raw material for the production of clinker, followed by sand, shale, iron ore, bauxite, fly ash and slag. About 2% gypsum is also added and then the mixture is pulverised. The resulting powder will react when water is added. Portland cement is commonly used to produce concrete, which is made of gravel, sand, cement and water. Blocks of cinder concrete, ordinary concrete and hollow tile are known as Concrete Masonry Units (CMU). They are larger than ordinary bricks and used for applications where appearance is not very important, such as in factory walls, garages and industrial buildings. One of the advantages of concrete blocks is that they can be reinforced, grouting the voids, inserting rebar or using grout, so that they are stronger than typical masonry walls.

Transcribed Image Text:The most common type of cement is Portland
cement, which is the basic ingredient of concrete
and mortar. It is made of Portland cement clinker
(calcium silicates, aluminium and other

Portland cement clinker is produced by heating a
mixture of raw materials up to 1450° C in a kiln.
There are three production stages: preparation of
the raw mixture, production of the clinker,
preparation of the concrete.
Limestone is the main raw material for the
production of clinker, followed by sand, shale, iron
ore, bauxite, fly ash and slag. About 2% gypsum is
also added and then the mixture is pulverised. The
resulting powder will react when water is added.
Portland cement is commonly used to produce
concrete, which is made of gravel, sand, cement
and water. Blocks of cinder concrete, ordinary
concrete and hollow tile are known as Concrete
Masonry Units (CMU). They are larger than
