Concrete Sampling BS EN 12350-1:2000, BS 1881

Sampling. BS 1881-108:1983 Testing concrete. Method for making test cubes from fresh concrete. Making, curing and testing cubes should be carried out in the correct manner. Even small deviations from the standard procedures will usually lead to compressive strength results which are lower than the true strength of the concrete.
