MEASUREMENT APPARATUS FOR AUTOGENOUS SHRINKAGE OF CONCRETE

摘要

An apparatus for measuring autogenous shrinkage of concrete is provided to measure the autogenous shrinkage by the variation of the probe of a measuring instrument, resulting in deeper analysis of the concrete characteristic. An apparatus for measuring autogenous shrinkage of concrete includes a prop(100), a concrete container(200), a shrinkage measuring instrument(300), and a measuring assistant member. The concrete container is installed on the prop, and has a hole on the upper part and measuring instrument insertion holes(210) on the sidewall. The shrinkage measuring instrument is installed on the prop, and has a probe(310) contacted with the concrete in the concrete container through the measuring instrument insertion hole. The shrinkage measuring instrument measures autogenous shrinkage of concrete by the variation of the probe. A part of the measuring assistant member is buried in the concrete and the other part is exposed through the measuring instrument insertion hole to be in contact with the shrinkage measuring instrument.
