摘 要:将钢渣掺入到水泥基体中,不仅起到增强作用,而且还可以改善其导电性。本文试验研究了钢渣水泥基材料在单轴压应力下的机敏性,并探讨了将其用作监测材料对混凝土内部损伤进行监控的可行性。结果表明,该导电混凝土在压应力作用下,电阻率的变化趋势可近似地符合二次多项式方程;随钢渣掺量增加,钢渣混凝土的机敏效应增强。 Abstract: A cement-based material, in which the steel slag is added for increasing the strength and improving the electro-conductivity, is tested for measuring the sensitivity of electro-resistance change under uniaxal compression. The rezults show that the change of resistance rate of concrete with compressive stress is approximately comformed to a quadratic equation, that is, as increasing of steel slag content, as intensifying of mechanical sensitivity of concrete. Besides, the feasibility of using this material as a supervisor for moniotring concrete's internal damage is discussed.

(1)钢渣掺入到水泥基体中,不仅可以起到增强效果,而且可以改善混凝土材料的导电性。掺入足够的钢渣导电相,将显著降低体系的电阻率。
(2)养护条件对钢渣混凝土的电阻率影响较大。电阻率在水养条件下增长缓慢,自然养护条件下增长迅速;养护温度升高,体系电阻率增大。
(3)钢渣混凝土具有压敏效应。对钢渣混凝土试块施于轴向压应力,当压应力较小时,电阻率随荷载增加而持续减小,两者具有一一对应关系;而随着压应力增大到一定程度后,电阻率反而有所升高,这与试件在压应力作用下产生微裂纹有关。
(4)不同质量组成的钢渣混凝土的压敏效应不同。钢渣混凝土的压力敏感性要比素水泥浆体高,随着钢渣掺量的增加,混凝土的压力敏感性增强。
