Discuss some of the most important considerations and strategies when proportioning concrete to ensure that the mixture will provide adequate workability and also good long-term performance. 7.

Solution

Concrete to give good workablity and long term performance:

1) aggregate texture should be round.

2) Water cement ratio should be adequate.(But not more)

3) By slightly changing the proprations of the fine and coarse aggregates.

4) Bigger size of aggregates will give more workbility.

5) Grading of aggregate provide better workablity and durability.
