Abstract
The main objective of this study is to detect the influence of the addition of limestone fillers in moderate percentages (0%, 10% and 20%) on the performance of binder formulations containing different dosages of blast furnace slag (ranging from 20% to 80%). The analysis parameters are mercury intrusion porosity and mechanical properties. The tests were performed on 12 blended pastes made with a water/cement ratio equal to 0.32. The mechanical properties of different pastes were investigated at several curing time (1 day, 7 days, 28 days and 90 days). The obtained results allowed estimating the possibility to benefit from the complementarity and synergy of the three components considered in the mechanical performance (compressive strength and dynamic Young's modulus) of ternary binders studied at both early age and mature age.
