The influence of aggregate stiffness on the creep of concrete

The influence of aggregate type and stiffness on creep behaviour of plain concrete for up to 6 months under load was studied. Three types of aggregate were used: quartzite, granite and andesite. Aggregate elastic modulus (stiffness) was measured and load and axial deformations were measured under compression. Six concrete mixtures were prepared using water/cement ratios of 0.56 and 0.4 for each of the three aggregate types. The compression strength of 100mm cubes cast for each mixture was measured. Concrete prisms were subjected to creep and shrinkage testing. The correlations between aggregate elastic modulus and creep were examined. No clear correlation was observed between the creep of concrete and the stiffness of the aggregate used in the concrete mixture.
