More DetailsAs far as the really long-term strength is concerned, American Portland cements made at the beginning of the century (which had a high C 2 S content and a low specific surface) led to an increase in the strength of concrete stored outdoors which was proportional to the logarithm of age up to 50 years. The 50-year strength was typically 2.4 times the 28-day strength.
