Preskusna metoda za upad: Uporabite žlico v obliki trobente z zgornjo odprtino 100 mm, spodnjo odprtino 200 mm in višino 300 mm ter napolnite beton v treh obrokih. Po vsakem polnjenju uporabite udarno kladivo, da 25-krat enakomerno udarite po steni vedra od zunaj proti notranjosti. Po nabijanju ga izravnajte. Nato dvignite vedro in beton se bo zaradi lastne teže sesedel. Razlika med višino žlice (300 mm) in višino betona po padcu je definirana kot pad. Če je razlika 10 mm, je padec 10.

The concrete slump should be determined based on the structural section of the building, the content of steel reinforcement, the transportation distance, the pouring method, the transportation mode, the vibrating capacity, and the climatic conditions. When selecting the mix proportion, comprehensive consideration should be given, and a smaller slump should be adopted.
The slump is applicable to concrete mixtures with high fluidity (slump value not less than 10mm, aggregate particle size not greater than 40mm). The consistency of concrete mixtures with a slump not exceeding 50mm or those of dry, hardened concrete and ultra-hardened concrete with a Weibull consistency exceeding 30s can be determined using the consolidation factor method.
