Analysis of compression resistance results of concretes
Description
The non respect of the rules specified on the standardisation and the consequent no conformity of the concretes leads the appearance of pathologies, arriving to a precocious degradation of the constructions. The collection of several specimens in five sites had as na objective to accomplish an “enlarged” statistiucal study, not only with the minimum number of specimens demanded by standards. The results were analysed with several combinations among them, respecting the minimum number of specimens demanded by standard, to verify probabilities existed of this to be respected. In four sites the cpncrete class obtained is superior to the demanded, while in one site to concrete did not verify the criteria. In this site, the classification of the quality control was médium, while in oither ones varied between good and very good. The classification was made taking in account the standard deviation of the results of the compression resistance test
