The consignment is considered to be the smallest batch to be examined 30 t of cement of the same grade and factory, with the same bagging date. The samples are taken by a commission at the construction site. From the batch of cement qualified in terms of quality, samples are taken of any chosen ones 20 bags after 1 kg from each bag. The samples are then mixed in a dry and clean place and divided into 2 samples after 10 kg each. You can use airtight tin vessels as packaging, and in their absence - cement bags of the same grade and date. The bags should be tightly tied, vessels well closed. Both bags, and the filled vessels should be sealed.
