The 'curing' of concrete by ponding is most effective for:
Choose the correct answer
Vertical concrete walls and columns
Horizontal flat surfaces like slabs and roads — water maintains contact over entire surface uniformly
Pre-cast elements in factory
Precast bridge girders
Correct Answer
B. Horizontal flat surfaces like slabs and roads — water maintains contact over entire surface uniformly

Curing methods: (1) Water curing — ponding (best for slabs), wet gunny bags, curing compounds; (2) Steam curing (precast — high temp = faster); (3) Membrane curing (spray chemical membrane). Ponding: most effective for flat horizontal surfaces (floors, road slabs) — water always in contact, uniform temperature. Not practical for vertical surfaces (use wet fabric / curing compound).
