Sampling of Freshly Mixed Concrete at the Field (BS EN ...

Apr 01, 2017  Sampling of fresh concrete at site. This British Standard specifies two procedures for sampling fresh concrete which are implemented by composite sampling and by spot sampling. Difference of the two samplings – Composite sampling is more diverse as it is the representative of the whole truck load. Scoopfuls are taken from four different parts of the load to form the standard sample.

Sampling the concrete

Sampling the concrete. Sampling should be in accordance with BS EN 12350-1, Testing fresh concrete. Sampling. Before sampling the concrete, it is important to make sure that it is fully mixed. A spot sample can be used to determine consistence (workability) but for all other sampling (e.g. for cubes) the composite sampling method must be used.

purpose of having more workable concrete, then the W/C ratio of the mix will be increased, causing the strength and durability of the concrete to be decreased.
