curing time of concrete 14-28 days
Yes, the vacuum dewatered concrete requires curing in order to gain its strength.The concrete is cured for 28 days.
It is the grade of concrete which indicates the strength of concrete after 28 days curing. M #) means the strength of concrete after 28 days of curing will be 30 N/mm2 .
All concrete need curing, since blinding is not structural concrete and treated as leveling course only, duration of curing may reduced. There is no specific period mentioned in relevant standard for curing of blinding.

It starts curing the second they put water in it.
minimum curing period of concrete is 21 days and maximum is 28 days

Curing compounds are used to slow or reduce evaporation of moisture from concrete. There are several curing compounds in use, but all form a membrane over the concrete's surface.

Curing in buildings is a process that is keeps freshly poured concrete from drying. It is kept at a certain temperature to keep it moist. Curing in buildings is important because it gives concrete what it needs to gain strength properly.
For proper curing
proper compaction and proper curing of the concrete gives good concrete. for compaction, it lessen the air voids or micro space between the aggregates of the concrete, those voids are very little which is not really visible. for curing, it lessen the heat of hydration of the cement.
The curing of concrete is a reaction between the type of cement in the concrete and the water. This reaction between cement and water is known as hydration. When the concrete sets and gains strength through this process it is known as curing. Test cylinders of concrete for construction projects are placed in a curing room where they are continuous misted with water at 23 +-2 degrees Celsius for 7 and 28 days before testing. This provides adequate curing.
