Which of the following statements is INCORRECT with respect to the workability of fresh concrete?
1
The fine, glassy pozzolanic materials offer better lubricating effects and give better workability.
2
The higher the water content per cubic meter of concrete, the higher will be the fluidity of concrete.
3
Flaky aggregate makes the concrete more workable than rounded aggregates.
4
The higher the aggregate/cement ratio, the leaner is the concrete.
