Study Notes
Fresh Concrete
- The strength of concrete is affected by the degree of its compaction.
- The consistency of the mix is crucial, as it enables the concrete to be:
- Transported
- Placed
- Finished
- Segregation-free
- Admixtures are used to achieve the desired consistency.
Test your knowledge on the impact of compaction on concrete strength, consistency, transport, placement, and segregation. Learn about the importance of mix consistency for the overall quality of concrete.
