(Job interview)

This is also one of the most important question asked in Civil Engineering Job Interview.

For this Question. Provide the definition of Concrete curing and point out the major steps and explain each of them in short. Please Check the explaination below.

Curing is the process of maintaining the moisture and temperature conditions for freshly deployed concrete. This is done for small duration of time to allow the hardening of concrete.

The various methods involved in the concrete curing process are as follows:

•Water curing

a) Sprinkling Method :- Shading concrete work than sprinkling of water on concreted surface. Used for ( Walls , Beams & Columns ). In General, walls, and columns can be cured by sprinkling water.

b) Ponding Method :- the horizontal surfaces including the slab and floors can be cured by stagnating the water.

c) Applying the chemical membrane on concreted surface.

d) Wet covering of surface: It can be cured by using the surface with wet gunny bags or straw

e) Curing Compounds: Easy to apply and inexpensive. Sprayer needed; inadequate coverage allows drying out; film can be broken or tracked off before curing is completed; unless pig- mented, can allow concrete to get too hot.

•Application of heat

a) Steam curing at ordinary pressure

b) Steam curing at high pressure

c) Curing by Infra-red radiation

d) Electrical curing.
