A comparison between mechanical propel-ties of self-compacting concrete and the corresponding properties of normal concrete

An experimental and numerical study on mechanical properties, such as strength, elastic modulus, creep and shrinkage, of self-compacting concrete (SCC) and the corresponding properties of normal compacting concrete (NC) is outlined in this article. The study included eight mix proportions of sealed or air-cured specimens with water-binder ratio (w/b) varying between 0.24 and 0.80. Half of the mixes studied were based on NC. The age at loading of the concretes in the creep studies varied between 2 and 90 days. Four different stress to strength levels were studied. Parallel studies were performed on strength (f(c)) and relative humidity (RH). The results show that elastic modulus, creep and shrinkage of SCC did not differ significantly from the corresponding properties of NC. The ongoing study was started in 1997.
