What strength is C50 concrete?

Coarse aggregates are made of rock quarried from ground deposits. The C grade in concrete determines the compressive strength, for example, C30 has the strength of 30 newton concrete, C40 has the strength of 40 newtons, C50 has 50 newtons strength.

What is C40 50 concrete?

C40/50. The 40 is the compressive requirement of 40 N/mm² of a crushed 100m concrete core and the 50 is a compressive requirement of 50 N/mm² for a crushed concrete cube. Therefore using the method of testing using concrete cubes, the tested compressive strength should be compared to the second number.
