The compressive strength of concrete is highly influenced by the properties of test specimens, such as size and moisture content. This paper presents the results of compression tests on more than 650 test specimens made with four different concrete types, which are mainly air‐entrained. The differences in compressive strength between different types of concrete specimens were investigated with similar...
In den letzten Jahrzehnten beruhen in Europa Schäden an Stahlbetonbauteilen vor allem auf einer ungenügenden Dauerhaftigkeit. Für eine ausreichende Dauerhaftigkeit muss ein Beton in der notwendigen Qualität fachgerecht eingebaut und nachbehandelt werden. Zudem ist die notwendige Bewehrungsüberdeckung sicherzustellen. Untersuchungen zeigten, dass trotz Vorgaben an die Betonzusammensetzung je nach Expositionsklasse...
