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 .
to control the haydration
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.
Shrinkage in concrete occurs due to the loss of moisture during the curing process. As the water evaporates, the concrete material contracts and reduces in volume. This shrinkage can lead to cracks forming in the concrete if not properly controlled. Factors such as mix design, curing methods, and environmental conditions can influence the extent of shrinkage in concrete.
curing time of concrete 14-28 days
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
Curing is necessary for freshly cast concrete in order to maintain the moisture as the chemical constituents in cement react with water and heat evolves continuously until the setting process completes. The heat evolved during the setting of concrete is called heat of hydration, and this heat causes the water to evaporate. Proper and complete setting process is the most important phenomenon that imparts the desired strength to the concrete. If the freshly cast concrete is not cured, it develops cracks and also the chemical reactions will cease resulting in bad concrete.
