What is
Cement Mortar,
Plain Cement Concrete (PCC)
And
Reinforced Cement Concrete (RCC)

Cement Mortar

A paste obtained by Adding water to fine Aggregates (Sand) and Binding material (Cement)
Cement Mortar is one of the most common and cheapest binding materials used in construction industry.
Cement mortar is basically a mixture of cement, sand & water.

Main uses of Mortar
To bind masonry units like stone, bricks, cement blocks.
To give neat finishing to walls and concrete works.
To fill joints and cracks in walls.
As a filler material in stone masonry.


Plain Cement Concrete (PCC)
The mixture of cement, fine aggregate (sand) and coarse aggregate (Small Stones) and water.
The size of the coarse aggregate (stones) used for PCC varies from 10-12 mm to 40 mm depending on where they are to be used.

Types of Concrete Mixing
Hand Mixing:
Mixing should be done on a masonry platform or sheet iron tray.
Machine Mixing:
Stones, sand and cement shall be poured/ mixed in a concrete mixer to maintain the required proportions.
Main uses of plain cement concrete

It is mainly used in construction of column foundation, Massive Gravity Dams, Flooring etc.
It is used in pavement construction (Roads)
It is also used in stone masonry works

Reinforced Cement Concrete (RCC)?
RCC means, it is stand for Reinforced Cement Concrete, which is a mixture of cement, sand & aggregate (stones) and steel bars.

Concrete has a very high compressive strength, but it is low in tensile strength.
Steel has a very high tensile strength (and also have good compressive strength).
Hence, when these two (concrete and steel) are combined together,
Such a material is known as Reinforced Cement Concrete.

Uses of rcc
Many different types of structures can be built using reinforced concrete including slabs, walls, beams, columns, foundations, frames and more.
