The Significance of Concrete Setting and Curing
The primary area to comprehend about concrete is the difference between setting and curing,
which is well understood by the professionals in construction industries in Lilongwe. Many
tend to avoid these terms' implication when working with them, which can have severe
repercussions. But if you tend to deal with concrete frequently, you must know how setting and
curing help extend concrete longevity by many months.
Concrete is said to have set when it gets stiffened to the point where it is able to absorb pressure
without facing any deterioration. One way to check is to walk on the new concrete surface; if it
leaves no footprint, it is set.
It generally takes a minimum of 2 hours for the concrete to set, depending upon the type of mix
and weather conditions. It sets more quickly in summers than in cold or freezing conditions.
What Happens When it Sets Too Quickly?
It may set too quickly in hot weather. However, it won't reach its maximum strength. Then it
may be prone to cracking, surface erosion, and wear and tear. Its lifespan may also get shorter.
That is why curing is necessary to escape such situations.
How to Cure Concrete?
Concrete can be cured in several ways. Keep the surface moist by sprinkling water either with
water or with a curing compound or a damp material such as sand.
Moreover, you can cover it with a protective surface such as polythene to ensure that the
moisture doesn't evaporate quickly.
