适用范围
This part of this British Standard contains the method by which the density of semi-dry, partially compacted concrete can be obtained for the purpose of determining the quantity of materials necessary to generate a volume of 1 cubic metre, also known as the “yield”. The method applies to plain concrete made with aggregate having a nominal maximum aggregate size, Dmax of 40 mm or less but not to concrete with a slump of more than 10 mm when tested in accordance with BS EN 12350-2. NOTE 1 The method for the determination of density of concrete with a slump of more than 10 mm is described in BS EN 12350-6. NOTE 2 This method is not applicable to concrete designed to conform to the requirements of the Specification for Highway Works [1] which describes a specific method for to be applied to hydraulically bound materials intended for use in highway pavements.
