Testowanie zgodności parametrów betonu innych niż wytrzymałość - teoria i praktyka
(2007) Kohutek, Zdzisław B.
Conformity testing of concrete properties has been introduced to the engineering practice by the PN-EN 206-1 European Standard. Previous national regulation (PN-88/B-06250) provided for no requirements; it also did not state any criteria in this respect. The European Standard provides for the separate procedure of conformity testing ot strength properties and separate for properties other than strength. The monitoring of conformity - separately for consistence and separately for group of other properties, like: density of light-weight concrete, density of heavy-weight concrete, water/cement ratio, cement content, air content and chloride content of concrete - have been presented in this publication. Each of the decribed procedures has been illustrated by a numeric example.

Testowanie zgodności parametrów wytrzymałościowych betonu
(Wydawnictwa AGH, 2009) Kohutek, Zdzisław B.
This article presents the principles of samples collecting and of appointing of concrete strength. It describes the procedures and criteria of conformity testing under norm PN-EN 206-1. Numerical examples along with groups of overlapping and non-overlapping consecutive results have also been contained in its contents. Final remarks explain the consequences of new defectiveness risk ratio. This article and the item [6] from bibliography bring the complete set of publications concerning the assessment of concrete properties conformity to an end.
