Measurement Apparatus for Thermal Stresses of Concrete Structures and Method Thereof

摘要

The present invention relates to a test device and method for measuring temperature stress. More particularly, the present invention overcomes the limitations of the measuring method of accessing a conventional analytical relates to temperature stress by the heat of hydration generated in the concrete structure to a measurement device that can be easily measured in a room.; The invention can directly measure changes in the temperature stress due to internal and external constraints that can occur in the concrete structures using the concrete of the coefficient of thermal expansion and other materials. In particular, the use of various materialization can estimate the temperature stress due to the degree constraint, it is possible to predict the temperature stress as it reflects the uncertain properties of early age concrete.
