In concrete structures there are basic methods used to increase strength of strucures, curing is the most factor structure design, construction engineer should follow to ensure concrete reach the desired compressive strength.
1- Continuous or frequent applications of water to the surface
· Ponding: it used mainly in
horizontal surfaces by applying by pond of water
· Continuous Spraying of water by sprinklers or any, avoiding alternate wetting and dryingand the application of cold water to warm concrete surfaces;
· Covering the surface with a
damp absorbent material like canvas fabric or any, usually adding water to
canvas two or three times per day.
2- Covering the surface to prevent water losses
· covering the surface with
an impermeable material such as polyethylene, which should be well sealed and
fastened
· spraying the surface with
an efficient curing membrane
· applying chemical compound to
the surface.
Curing Period
Curing shall continue to a period not less than 7 days, so
concrete can reach 70% of its compressive strength.
