composition of concrete
The basic components of concrete are water cement gravel sand and air
Cement acts as a primary binder to join the aggregate into a solid mass.
Water is required for the cement to hydrate and solidify.
Joseph Aspdin of England invented Portland cement by burning chalk with clay until carbon dioxide was driven off.
Concrete is easy to mould, non-combustible hard material and can be produced locally in
one large concrete monolithic structure and the quality can be adapted to the goal of the structure.

from soft (lime and sandstone) to very hard (granite) and in all colours and structural appearances.
