Firstly, the reference C32/40 relates to the characteristic strength of the concrete. In this case to confidently achieve 40N/mm 2 from standard cubes tested at 28days, (32N/mm 2 for standard cylinders) with a statistical 95% confidence limit, the mean strength of the population will be approximately 7N/mm 2 above the specified characteristic i ...
As a standard mark, it takes 28 full days for your concrete to be fully cured. At the 7 day mark your concrete will be at around 70% strength. For concrete to set though it is between 24 – 48 hours. See more information below. Get a FREE quote, tap here or call: 0208 751 0101.
