钢渣砂浆的交流电阻率特性

Ac Resistivity Characteristics of Steel Slag Mortar

通过对钢渣砂浆电阻率及无侧限抗压强度的测定,研究了交流电流频率、龄期、钢渣掺量对砂浆试件电阻率的影响,并且对钢渣砂浆无侧限抗压强度与电阻率的关系进行了分析。分析结果表明,在50 Hz^50 k Hz范围内时,交流电流频率对钢渣砂浆的电阻率影响较大;在50 k Hz^1 MHz范围内时,随着电流频率的增大,试件的电阻率变化趋于平缓。钢渣砂浆试块电阻率随养护龄期的增大而增大,随钢渣掺量的增加总体呈减小趋势。钢渣砂浆的无侧限抗压强度随钢渣掺量的增加而减小,与电阻率之间存在正相关关系。

Through to the steel slag mortar resistivity and the determination of the unconfined compressive strength, the alternating current frequency, age and steel slag content on the influence of the mortar specimen resistivity, and the unconfined compressive strength of steel slag mortars and the relationship between the resistivity is analyzed. Analysis results show that, within the scope of 50 Hz -50 kHz, alternating current frequency to greater effects on the resistivity of steel slag cement mortar; In 50 kHz - 1 MHz range, with the increase of current frequency, the resistivity changes of the specimens was flat. Steel slag mortar test block resistivity increases with the curing age, while overall showed a trend of decrease with the increase of the dosage of steel slag. The unconfined compressive strength of steel slag mortar decreases with the increase of the dosage of steel slag, and there is a positive correlation relationship between resistivity.
