Shrinkage is definitely a crucial parameter for long-term sustainability of cement paste, mortar and concrete structures. This paper examines the correlation between different shrinkage parameters of paste and mortar with different percentage of limestone fines (LF). Furthermore, the correlation between each shrinkage parameter and compressive strength, and between expansion and compressive strength are also investigated. In the experimental program, cement was substituted with different percentages of LF (0, 5, 10, 15 and 20% by mass). For paste and mortar mixtures, the water to binder ratio (w/b) was 0.45 and the sand to binder ratio (s/b) was 2. Results indicated that there is a positive linear relationship between length change and the percentage weight change. Similarly, there was a positive correlation between expansion and compressive strength for pastes and mortars. However, there was a negative correlation occurring between both shrinkage parameters and compressive strength. As shrinkage increased, the compressive strength dropped.
