Natural hydraulic lime for blended cement mortars: Behavior from fresh to hardened states

This paper presents the influence of natural hydraulic lime (NHL) on the behavior of cement-based materials at fresh and hardened states. Two reference mortars with and without limestone filler (LF) and with water-to-cement ratio of 0.6 were considered. For each reference mixture, cement was replaced by NHL with increasing mass proportions of 12.5%, 25% and 50%, while maintaining a constant paste volume. The freshly mixed pastes and mortars were...
