Concrete quality control and quality assurance
Pages 16

In order to obtain better control of the high scatter and variability of achieved construction quality typically observed (Chapter 2), it is essential to have some performance-based durability requirements that can be verified and controlled for quality assurance during concrete construction. Even for the offshore concrete structures where the strictest procedures for both concrete production and quality control during concrete construction were applied, these concrete structures also partly showed a high scatter and variability of achieved construction quality. Although the regular concrete quality control typically revealed a very homogeneous concrete production (Table 2.1), a high scatter and variability of achieved in situ quality of the concrete could still be observed (Figure 2.61).
