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 stren gth, elastic modulus, creep and shrinkage, of self-compacting concrete (SCC ) and the corresponding properties of normal compacting concrete (NC) is ou tlined 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 a nd 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 diffe rent stress to strength levels were studied. Parallel studies were performe d on strength (f(c)) and relative humidity (RH). The results show that elas tic modulus, creep and shrinkage of SCC did not differ significantly from t he corresponding properties of NC. The ongoing study was started in 1997.
