Compressive strength of M25 concrete after 7 days & 28 …
The compressive strength of M25 concrete after 7 days is typically around 65% of its 28-day strength. For M25 grade concrete, the target compressive strength at 28 days is approximately 25 megapascals (MPa). Therefore, you can expect the compressive strength after 7 days to be around 16.25 MPa. Hi guys in this article we know about …
