Consider the following statements:1) workability of concrete increases with the increase in the proportion of water content2) Concrete having small-sized aggregates is more workable than that containing large-sized aggregate3) For the same quantity of water, rounded aggregates produce a more workable concrete mix as compared to angular and flaky aggregates4) A concrete mix with no slump shown in the slump cone test indicates its very poor workabilityWhich of the above statements are correct?
