Researches on the Strength and Electrical Conductivity of Carbon Fiber Steel Slag Micro-powder Cement Mortar

设计完成碳纤维含量为0.6%,钢渣微粉含量分别为0%、10%、20%、30%、40%、50%、60%的碳纤维钢渣微粉导电砂浆试件。探讨钢渣微粉掺量对碳纤维导电砂浆试件的抗折强度、抗压强度与电阻率的影响。结果表明:在钢渣微粉掺量为30%以内时,钢渣微粉对碳纤维导电砂浆试件的抗压强度、抗折强度影响较小;在碳纤维导电砂浆试件中加入钢渣微粉,能改善碳纤维导电砂浆试件的导电性能。通过在碳纤维导电砂浆中掺入30%以内的钢渣微粉,能制备出力学性能和导电性能良好的碳纤维钢渣微粉导电砂浆,降低水泥的使用量,节约成本。

Carbon fiber steel slag micropowder conductive mortar specimens with carbon fiber content of 0.6% and steel slag micropowder content of 0%, 10%, 20%, 30%, 40%, 50%, and 60% were designed and completed. The effects of steel slag micropowder content on the flexural strength, compressive strength and resistivity of carbon fiber conductive mortar specimens were discussed. The results show that: when the content of steel slag powder is less than 30%, the effect of steel slag powder on the compressive strength and flexural strength of carbon fiber conductive mortar specimens is small;adding steel slag powder to carbon fiber conductive mortar specimens can improve the carbon fiber conductive mortar test electrical conductivity of the parts. By adding less than 30% steel slag micropowder into carbon fiber conductive mortar, carbon fiber steel slag micropowder conductive mortar with good mechanical properties and electrical conductivity can be prepared, reducing the usage of cement and saving costs.
