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 the determination of resistivity and unconfined compressive strength of steel slag mortar, the influence of AC current frequency, age and steel slag content on the resistivity of mortar specimens was studied. And the unconfined compressive strength and resistivity The relationship was analyzed. The results show that the AC current frequency has a great influence on the resistivity of steel mortar in the range of 50 Hz ~ 50 k Hz. With the increase of the current frequency in the range of 50 k Hz ~ 1 MHz, Resistivity changes tend to be gentle. The resistivity of slag mortar increased with the increase of curing age, and decreased with the increase of slag dosage. The unconfined compressive strength of slag mortar decreases with the increase of steel slag content, and there is a positive correlation between resistivity.
