Concrete quality control on site in Italy is generally poor: lack of reliable execution specifications and inspection practices is one of the causes. Concepts introduced by recent standard UNI EN 13670 give the opportunity of change: the fulfilment of specific requirements may improve significantly the actual situation. QC management options, namely concerning execution and curing classes are outlined. A r.c structures effective inspection plan should rely on a detailed coordinated concreting planning : basic criteria for its drafting are illustrated. Systematic analysis of records of real quantities of components batched and times printed in delivery tickets can help to better check on site compliance of actual w/c ratio with specified values and prevent problems arising during unloading and placement.
