摘要
研究了掺纤维水泥砂浆升温与降温过程中的热电效应,并着重探讨了纤维和水泥基体对该体系热电性能的影响.研究发现:碳纤维和微细钢纤维能显著提高和改善水泥砂浆的热电性能;通过碳纤维水泥砂浆与微细钢纤维水泥砂浆联结可形成水泥基热电偶,从而实现对大体积水泥砂浆混凝土内部的温度监控.
The thermoelectric property of cement mortar with fiber was measured and studied during the heating and cooling process. The effect of fibers and cement mortar on thermoelectric property (Seebeck effect) were focused on especially. It is found that the fiber addition increases the linearity and reversibility of the Seebeck effect in the cement mortar. The cement-based thermocouples with sensitivity up to 70 uV/℃ can be got by using junctions made by pouring carbon fiber cement mortar and micro steel fiber cement mortar side by side.
