Curing Compound

Why Concrete needs curing: - Concrete needs to maintain the temperature at the time of heat of hydration. Without going much technically, when cement is mixed with water there is a chemical process and lots of heat is generated, and the hot gases are the reason for cracks, to maintain the temperature curing is done for its complete process. it lay a layer/film on the surface which does not allow its water to evaporate and additionally it makes the surface cool.

Advantages of Curing Compound.

Sr. No

Advantages

1

Reduce the plastic cracks in concrete which occur incedingly

2

To get the strength of the concrete of the desired level

3

Low Shrinkage due to continuous moisture

4

Due to the layer of compound, the cement dust does happen and it dust-free

5

Frost resistance increase

6

Water is saved in huge quantity

 

Usage of the Material.

It's high depending on weather conditions, if it's too hot you will need more curing compound, and if it's low then less, however, 5 to 6.5 m2 per liter is considered in normal cases.
