This paper reports the observed deformation composed of autogenous shrinkage (AS) and thermal expansion/contraction in high-strength concrete with water-binder ratio of 0.4-0.2. While AS in concrete with Portland cement subjected to high temperature history becomes smaller than that under 20°C, AS in concrete with blended cement becomes larger when amount of the additives is large. By taking increase of thermal expansion coefficient with age into account, it may be able to estimate the composed deformation in high-strength concrete structures.
