Micro structure of Concrete


Research has made it possible to significantly improve the strength and durability of concrete without a great increase in cost. As a result of the research “Concrete technology” has under gone from a macro to a micro level study in the enhancement of strength and durability. By bringing about changes in the micro structure of concrete, strength of concrete as a whole can be improved.

The Magnetic Resonance Imaging (MRI) of a concrete block clearly indicates three components of which concrete is made of. Hence the three components of which a concrete hardened block is made up are:

1. Hardened Cement Paste (HCP)

2. Aggregate

3. Transition zone: Weakest zone (Extensive research is being made to improve properties of this zone)

Summary:

Knowledge of the micro structure and properties of the individual components of concrete and their relationship to each other is useful for exercising control on the properties of Concrete.
• It is possible to modify the properties of concrete by making suitable changes in the micro structure.
