This study assessed 40 industrial clinkers from 16 cement plants, determining their physical, chemical, and mineralogical properties and the corresponding cements' strength development and hydration kinetics. Pearson's statistical analysis identified key factors influencing clinker and cement properties. Clinker composition ranged within 56.5–73.9% C₃S, 4.1–24.5% C₂S, 0.8–8.4% C₃A, and 7.4–13.9% C₄AF. The sulfate-alkali ratio significantly impacted C₃A content and polymorphism. Alite crystal size was directly influenced by the CaO content and the sulfate-alkali ratio and inversely by the MgO, K₂O, and F− contents. Clinker grindability was directly affected by the C₃S crystal size and the sulfate-alkali ratio while inversely impacted by the MgO and K₂O contents. Key parameters for early cement hydration included fineness and K₂O content (positive) and C₃S crystal size (negative); larger C3S crystal size negatively affected cement early strength, while MnO2 and K2O presence improved 1-day strength. For 28-day strength, increasing cement fineness and K2O content were detrimental.

揭示熟料反应性和水泥性能的关键因素：40 种工业熟料的物理化学和性能调查


本研究评估了来自 16 家水泥厂的 40 种工业熟料，确定了它们的物理、化学和矿物学特性以及相应的水泥强度发展和水化动力学。Pearson 的统计分析确定了影响熟料和水泥性能的关键因素。熟料成分范围为 56.5-73.9% C₃S、4.1-24.5% C₂S、0.8-8.4% C₃A 和 7.4-13.9% C₄AF。硫酸盐碱比显著影响 C₃A 含量和多态性。铝榴石晶体尺寸受 CaO 含量和硫酸盐碱比直接影响，而 MgO 、 K₂O 和 F− 含量则反比影响。熟料的可磨性直接受 C₃S 晶体尺寸和硫酸盐-碱比的影响，而 MgO 和 K₂O 含量则受其负影响。早期水泥水化的关键参数包括细度和 K₂O 含量（正）和 C₃S 晶体尺寸（负）;较大的 C3S 晶体尺寸对水泥早期强度产生负面影响，而 MnO2 和 K2O 的存在提高了 1 天强度。对于 28 天的强度，增加水泥细度和 K2O 含量是有害的。
