Effect of triisopropanolamine (TIPA) on compressive strength and hydration properties of cement-lithium slag (LS, 30%) paste was studied. The results demonstrated that the addition of TIPA is advantageous for compressive strength at 7 d, 28 d and 60 d. The reason was related to the pore complexity and hydration process of cement and LS. TIPA reduced the total porosity, and increased the fractal dimension, making the pore structure more complicated. In addition, TIPA promoted the pozzolanic reaction of LS and the hydration of cement, expediting the formation of C–S(A)-H gel. TIPA accelerated the dissolution of aluminate ions, silicate ions and ferric ions in the pore solution, thereby accelerating the pozzolanic reaction of LS. During the hydration of cement-LS paste, TIPA facilitated the conversion of ettringite to the AFm-like phase and produced more C-A-S-H gel by promoting the dissolution of aluminate ions.

研究了三异丙醇胺（TIPA）对水泥锂渣（LS，30％）浆体的抗压强度和水化性能的影响。结果表明，添加TIPA有利于7 d，28 d和60 d时的抗压强度。原因与水泥和LS的孔隙复杂性和水化过程有关。TIPA降低了总孔隙率，并增加了分形维数，从而使孔结构更加复杂。此外，TIPA促进了LS的火山灰反应和水泥的水合作用，加速了C–S（A）-H凝胶的形成。TIPA加速了铝酸盐离子，硅酸盐离子和铁离子在孔溶液中的溶解，从而加速了LS的火山灰反应。在水泥-LS糊的水化过程中，
