Is there any chances of shrinkage or any other types of cracks formation in concrete if concrete attains its 110% strength in 7 days and little bit increment around 5mpa in 28 days by using admixtures? Its actually M40 grade concrete in which 7days strength is 44Mpa and 28days strength is around 52-56Mpa.

Achieving high strength in concrete, such as 110% in 7 days and incremental strength gain in 28 days, can increase the potential for shrinkage and cracking. While admixtures can help mitigate these issues, it is important to work with experts to optimize the mix design and select the appropriate admixtures to minimize the risks.

Thank you sir for your reply. Actually in my concrete structures no any issues of cracking and shrinkage have appeared till now(It's almost 4-5 months but nothing happened) but some people are telling that cracks and shrinkage may appear in long term duration. So that thing i want to confirm whether it's like that or not.
