摘要
In the design and in the planning of execution of reinforced concrete members, knowledge of the concrete properties at both fresh and hardened state is crucial. The present research compares the behaviour of three different types of Limestone Self-Compacting Concrete designed for a 28days compressive strength of 40, 75 and 90MPa, respectively. After investigating the main properties at the fresh state in terms of flowability, viscosity and segregation resistance, the study focuses on both the stress-strain behaviour under uniaxial compression and on the bond properties of all the mixes. Finally, the results are compared with existing design provisions for normal vibrated concrete.
