C40/50 of concrete strength is saying that 40Mpa(by using cylinder specimen) and 50Map (by using cub.. Answer / d.kim I believe that C40/50 is about Characteristic concrete strength and target mean concrete strength is more higher than 40map(50map).
The primary benefit of entrained air in hardened concrete however is the resistance it offers to freeze-thaw damage and scaling caused by de-icing salts or chemicals. Most concrete contains some moisture which expands during freezing temperatures.

Jan 04, 2013· From the graph we can clearly say that 30 MPa is the characteristic strength of the given concrete mix. The value of fck is lower than fcm (40 MPa- mean strength) by 1.64σ, where σ is the standard deviation of the normal distribution. So we can say the given concrete mix has a characteristic strength of 30 MPa or it is a M30 grade mix. M- Mix

Concrete is effectively an artificial stone or rock. Its primary properties are that is is workable before hardening, strong in compression and stays strong for extremely long timescales. Concrete is a strong hard building material composed of sand and gravel and cement and water.
C40/50. The 40 is the compressive requirement of 40 N/mm² of a crushed 100mm concrete cylinder 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 mix design M-50 grade (Using Admixture –Sikament) provided here is for reference purpose only. Actual site conditions vary and thus this should be adjusted as per the location and other factors. Parameters for mix design M50. Grade Designation = M-50 Type of cement = O.P.C-43 grade Brand of cement = Vikram ( Grasim )
A C40 mix has a high cement content inclusion, meaning that the strength of the mix is in the high class of the design concrete products that we offer. This would be used when strength is the main factor of your concrete application.
