Applications of Fiber Grating in Temperature Measurement of Hydration Heat of Concrete
In order to verify the application effect of fiber grating strain gauge in concrete hydration heat measurement, the relevant experimental researches were carried out. First, according to the formulas of concrete condensation hardening adiabatic temperature rising, the regulation of temperature changes in the concrete condensation hardening process was calculated. Then the observation results of concrete condensation hardening temperature by fiber grating were analyzed, and the variation regulation observed was summarized, and the variation regulation was verified by temperature sensors embedded in the corresponding positions. The results of the study shown that, the measured data by fiber grating can reflect the temperature change rule of concrete well. Therefore, it was feasible to measurement the temperature change regulation by fiber grating.
