This study investigates the creep properties of limestone calcined clay cement. A series of paste samples using limestone and calcined clays as replacement materials were tested under basic compressive creep. The ternary mixes showed lower creep compliance than the plain cement references, even when using low reactivity clays or lower replacement fraction. A finite element model was used to back-calculate the visco-elastic properties of the C-S-H matrix and C-S-H gel. Whereas the elastic properties of C-S-H were found to be similar between LC3 and plain cement, the viscous behaviour of C-S-H gel appeared to be noticeably different for LC3. |
