Abstract: A shrinkage measurement apparatus for a concrete specimen is provided to measure shrinkage of a pure concrete and to facilitate use thereof. A shrinkage measurement apparatus for a concrete specimen(1) includes a supporting unit(10), a slant forming unit(100), a propping unit(20), a measuring instrument mounting unit(30), and a shrinkage measuring instrument(40). The supporting unit supports the concrete specimen upward. The slant forming unit is formed in the upper part of the supporting unit so that the concrete specimen is mounted at a predetermined slant. The propping unit prevents separation due to sliding of the concrete specimen, which is formed on the end of a down slant side of the concrete specimen. The measuring instrument mounting unit is formed in the opposite side of the propping unit about the concrete specimen. The shrinkage measuring instrument measures the shrinkage of the concrete specimen, which is installed in the measuring instrument mounting unit.
