Varying strength values measured at the ready-mixed concrete plant and on the construction site, particularly for F5/F6 concretes – which party is liable?

For control purposes concrete is normally required to be tested under uniaxial compression, indirect tension and flexure. In view of the importance of concrete cube, cylinder and core testing within...

1 Introduction The spectrum of normal weight concretes covered by DIN EN 206 [1] and DIN EN 1992-1-1 [2, 3] ends at compressive strength class C100/115 in Germany at present. The characteristics...

Mortar and concretes with a compressive strength of up to 800 N/mm² are currently under development. Typical fields of application of high-strength concrete and high-performance concrete are: »...

1 Theoretical principles of concrete compaction The fresh concrete to be produced is composed of cement, aggregate of different particle sizes, mostly between 0.25 to 32 mm, and mixing water. Today,...
