红外热像用于水泥砂浆火灾损伤的检测与评定

Use Infrafed Thermal Image for Testing and Evaluating on Fired Damage of Cement Mortar

基于红外检测技术的原理和特点，采用红外热像技术对水泥砂浆试件火灾损伤的红外热像特征进行了实验研究，得出普通水泥红外热像平均温升的变化曲线及其与表面受灾温度及强度损失的回归方程，并对火灾水泥石的显微结构进行了分析．

Based on the principle and chaacteristics of idfrared testing technology, the inrared thermal image characteristic of fired cement mortar is researched by using infrared thermofraphy in the paper. The change curves of average rising temperature on infrard thermal image of cement mortar is obtained, and the regressive equations of average rising temperature of infrared thermal image to the fired temerature and the loss of strength of ordinary cement is established, and micro-structure of fired cement is analyzed.
