بيت /what is the crushing strength of m concrete at seven days
Compressive strength of concrete at 07 days should be in the range of 60 to 70% of its characteristic compressive strength. The 28th day strength is also known as the characteristics strength In the grade of concrete, the 28th day strength is expressed in N/Sqmm. as a digit after the M.

From above table, we see that, concrete gains 16 percent strength in one day, 40 percent in 3 days, 65% in 7 days, 90% in 14 days and 99% strength in 28 days. Thus, it is clear that concrete gains its strength rapidly in the initial days after casting, 90% in only 14 days.
