Hardened material properties of self‐compacting concrete

Journal of Civil Engineering and Management, 2004
Selfâ€compacting concrete (SCC) is an innovative construction material with a favourable rheological behaviour, which is caused by its modified concrete composition. Based on this fact SCC offers improved fresh concrete but also hardened material properties and therefore many advantages regarding the productivity and the design potential compared with ...
