Curing compound is primarily used for reducing the loss of moisture from freshly-placed concrete and it is applied once after concrete finishing is completed. Sealing compounds is adopted to retard the entrance of
damaging materials into concrete and they are normally applied after the concrete is placed for 28 days. The harmful substances include water, deicing solutions and carbon dioxide which eventually cause freeze-thaw
damage, steel corrosion and acid attack respectively.
This question is taken from book named – A Closer Look at Prevailing Civil Engineering Practice – What, Why and How by Vincent T. H. CHU.
