The figure-1 below shows the strength variation of a concrete present at dry and wet condition. This graph is based on the study conducted by Baykof and Syglof (1976). They found that, in dry conditions, after 1 year there is no increase in concrete strength, as shown,What is the crushing strength of M50 grade concrete? - Quora,Answer: Crushing strength is another term for compressive strength. M50 denotes concrete mix with a characteristic cube compressive strength (denoted by fck) of 50 N/square mm or 50 MPa. In other words, M50 grade concrete possess a crushing strength of 50 N/square mm or 50 MPa. (Source of image...What is the crushing strength of a cube of M30 concrete,,Answer: As per IS 456 , M30 grade concrete is designed for strength = fck + 1.65 x standard deviation ; where , fck = 30, standard deviation = assumed values given in IS 456 Above strength value should be achieved in the lab while preparing the Design Mix.
