研究了三乙醇胺(TEA)对掺钛矿渣(占胶凝材料总量的50%)的水泥浆体和砂浆的强度发展和水化性能的影响。采用等温量热、非挥发水含量和压汞孔隙率(MIP)等技术表征了不同龄期的水化过程。结果表明：1)掺入0.01%~0.10%的TEA对掺钛矿渣水泥砂浆的强度发展有积极的促进作用，表现为抗压强度和抗拉强度的提高；2)TEA使28d前等温量热和非蒸发水含量测定的水化程度增加；3)TEA降低了掺钛矿渣水泥浆体的累积孔隙率。因此，0.01%~0.10%的TEA促进了钛渣的水化，形成了更多的凝聚结构，从而促进了共混体系的强度发展。
This paper investigates the influence of triethanolamine (TEA) on strength development and hydration of cement pastes and mortars incorporated with titanium slag (50% by mass of the total cementitious materials). The techniques including isothermal calorimetry, non-evaporative water content, and mercury intrusion porosimetry (MIP) were employed to characterize the hydration process at varied ages. The results show that: 1) 0.01%~0.10% addition of TEA has a positive effect on the strength development of blended cement mortars with titanium slag indicated by improved compressive strength and tensile strength; 2) TEA leads to an increase of hydration degree determined by measurement of isothermal calorimetry and non-evaporable water content before 28 d; 3) the cumulative porosity of cement pastes incorporated with titanium slag was reduced by TEA. Therefore, 0.01%~0.10% addition of TEA promotes the hydration of titanium slag, then forming more condensed structures, thus enhance the strength development of blended systems.
