With the increase in the strength level of concrete (C30, C40 and C50), the effective bond length of interfaces increased. When the strength of the concrete increased by one level, the increased amplitude of the effective bond length was approximately 13%.
For C20~C40 concrete, the air content increases with addition of air entraining agent, while a maximum air content value appears for C50 concrete. The compressive strength of C20 decrease slightly with the air content, on the other hand, that of C40 significantly decreases relatively.
Mar 31, 2012· In the Eurocode, concrete's compressive strength is specified as CXX/XX ( C30/37), in MPa. The first number is for compressive testing done in a 150 mm diameter and 300 mm high cilinder, the secondo one is for a 150 mm cube.

that the free water of C30 concrete had completely evaporated at K. And with increasing temperature, the deformation difference increased gradually between cement colloid and coarse aggregate and the interface cracks continued to expand. As a result, the strength declined sharply. The strength of C40 MSC turned to rebound a bit at 473 ...
