Introduction |
| |
The
strength of any given concrete is inversely related
to the water/cement ratio. Low the water content
increases the strength of the concrete. Water is
an essential ingredient of concrete where it plays
two basic roles:
 |
it
gives concrete the required rheological properties
and |
|
it
participates in the reaction of hydration. |
The ideal concrete should thus only contain the
minimal quantity of water necessary to develop the
maximum possible strength of cement while providing
sufficient workability for placement. However, since
cement particles have a strong tendency to flocculate
when they are brought in contact with water, it
is necessary to add more water than is necessary
in order to obtain a certain level of workability.
Since this additional water will never be in the
hydration reaction, it will generate porosity within
the hydrated cement paste, resulting in a weakening
of the mechanical properties of concrete and in
a decrease of its durability.
All this can be achieved by adding admixtures like
Superplasticizers,Water Reducers etc. |

Superplasticizers |
| |
Superplasticizers
are powerful dispersing agents. As with most dispersing
agents in aqueous solutions, they first act by being
absorbed onto the surface of cement particles. With
superplasticizers water reducing can reach about
20 to 30%. Very highly workable even flowing concrete
can be produced.
