Q. Consider the following statements:

Q. Consider the following statements:
1. If more water is added to concrete for increasing its workability, it results in concrete of low strength.
2. No slump is an indication of good, workable concrete.
3. Higher the slump of concrete, lower will be its workability
4. Workability of concrete is affected by water content as well as water-cement ratio.
Which of the above statements are correct?

Q. Consider the following statements :
1. Workability of concrete increases with the increase in the proportion of water content
2. Concrete having small-sized aggregates is more workable than that containing large-sized aggregate
3. For the same quantity of water, rounded aggregates produce a more workable concrete mix as compared to angular and flaky aggregates
4. A concrete mix with no slump shown in the slump cone test indicates its very poor workability
