Relationships between supplementary cementitious material (SCM) pozzolanic reactivity, bulk electrical resistivity, and alkali-silica reaction expansion were examined for traditional and non-traditional SCMs using the modified R³ test, bulk resistivity measurements, and the accelerated mortar-bar test (AMBT), respectively. The SCMs included pozzolanic pumice and glass powder and latent hydraulic slag, with cement and limestone fillers being tested as controls. For mixtures with SCMs, as fineness, reactivity, or replacement level increased, bulk resistivity increased, and the ASR expansion decreased; this was not the case for limestone. Strong correlations between pozzolanic reactivity, bulk resistivity, and ASR expansion suggest the ability to estimate expansion based on reactivity and resistivity, although ASR expansion is a more complex phenomenon. By increasing the curing temperature, 1-day bulk resistivity measurements could be used to estimate ASR expansion. Threshold values for bulk resistivity and pozzolanic reactivity were proposed for screening materials and mixtures, including novel ones, for ASR durability.

^{使用改进的 R 3检查了传统和非传统 SCM 的}辅助胶凝材料(SCM) 火山灰反应性、体积电阻率和碱-二氧化硅反应膨胀之间的关系测试、体积电阻率测量和加速砂浆棒测试 (AMBT)。SCM 包括火山灰浮石和玻璃粉以及潜水性矿渣，水泥和石灰石填料作为对照进行测试。对于含有 SCM 的混合物，随着细度、反应性或置换水平的增加，体积电阻率增加，ASR 膨胀降低；石灰石并非如此。火山灰反应性、体积电阻率和 ASR 膨胀之间的强相关性表明可以根据反应性和电阻率估计膨胀，尽管 ASR 膨胀是一种更复杂的现象。通过提高固化温度，1 天体积电阻率测量可用于估计 ASR 膨胀。
