| Abstract: | Based on the comparatively experimental study on four groups of high-strength concrete made of different combinations of two fine aggregates(machine-made and natural sand) and two coarse aggregates(crushed limestone and granite),the effects of the fine and coarse aggregates on the autogenous shrinkage of high-strength concrete are analyzed.The formulas are proposed for predicting the autogenous shrinkage of high-strength con-crete of different aggregates. |
