Abstract:
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.
