Abstract
A reliable technique to quantify autogenous strain is a prerequisite to numerical modeling in stress calculations for high performance concrete. The introducing of a special kind of corrugated tube mould helps to transforming volume strain measurement into liner strain measurement in horizontal direction for fluid concrete, which not only realizes the continuous monitoring of the autogenous shrinkage since casting, but also effectively eliminates the disturbance resulting from gravity, temperature variation and mould restraint on measuring results. Based on this measuring technique, this paper systematically investigates the influence of material properties, size and internal air of the corrugated tube on the measuring results. The effect of measuring directions and bleeding water on the measurement results is also studied and the mechanism is discussed.
