Recently developed reactivity tests for supplementary cementitious materials (SCMs) have shown the ability to differentiate between inert and reactive materials. Two promising SCM reactivity tests were used to study ten different SCMs. The first method involves quantifying the heat release, bound water, and calcium hydroxide consumption of SCMs in a simulated pore solution (modified R³ test), and the second method is a lime strength test that quantifies lime mortar strength development. Tests on cementitious pastes with a 20% SCM replacement level were conducted to determine heat release, calcium hydroxide content, bound water, compressive strength, and bulk resistivity for 35 days. Moderate correlations between the modified R³ heat release at 10 days and 1 day and between modified R³ heat release and bound water were shown, which suggests the possibility of reducing test duration and using bound water, instead of the heat release. The calcium hydroxide consumption measured from the modified R³ test correlates strongly with CaO content in the SCM and moderately to paste bulk resistivity at 35 days, demonstrating the fundamental importance of measuring calcium hydroxide consumption. Correlations between modified R³ heat release and bound water and most other paste properties were generally poor, presumably because of the high acceleration in the modified R³ tests. The compressive strength measured from the lime strength test showed moderate to strong correlation to heat release, calcium hydroxide content, bound water, and bulk resistivity of cementitious paste at 1–35 days. The fundamental importance of these reactivity tests is therefore clearly validated.

最近开发的补充胶凝材料（SCM）的反应性测试表明，可以区分惰性材料和反应性材料。两项有前途的SCM反应性测试用于研究十种不同的SCM。第一种方法涉及量化模拟孔隙溶液中SCM的放热，结合水和氢氧化钙的消耗（改进的R ³测试），第二种方法是对石灰砂浆强度发展进行量化的石灰强度测试。对具有20％SCM替代水平的水泥浆进行了35天的热释放，氢氧化钙含量，束缚水，抗压强度和体积电阻率测试。修饰的R ³在10天和1天的放热与修饰的R之间的中等相关性^{显示了3个}放热和结合水，这表明可以减少测试时间并使用结合水代替放热。通过改进的R ³试验测得的氢氧化钙消耗量与SCM中的CaO含量密切相关，并在35天时适度地粘贴了体电阻率，这证明了测量氢氧化钙消耗量的根本重要性。改性R ^3的热释放与束缚水之间的相关性以及大多数其他糊状物的性能通常较差，这可能是由于改性R ³的高加速度测试。石灰强度试验测得的抗压强度与热释放，氢氧化钙含量，结合水和水泥浆在1–35天的体积电阻率呈中等至强相关性。这些反应性测试的根本重要性因此得到了明确验证。
