I've heard about it... Any knowledge?

Yes it is known as efflorescense ...its build on concrete surfaces due to moisture coming from ground. It supposedly not hazardous and can be clean with vinegar water but problem is its a sign that the basement floor or concrete was not sealed properly by the builder..

Interesting...
Thank you for the information
