Curing of concrete means

  • A.keeping it moist and warm enough for hydration to continue
  • B.allowing it to dry out just as quickly as it possibly can
  • C.applying full load to it as soon as it has finished setting
  • D.removing the formwork at the very earliest possible moment

Answer: A

Hydration stops if the paste dries, and strength gain stops with it, permanently. Poor curing is among the commonest causes of concrete failing to reach the strength its mix design promised. Curing is cheap to do well and expensive to get wrong.
