The effects of a range of calcination heating rates (50°C/h, 100°C/h, 150°C/h, 200°C/h) to binders’ reactivity, yield, maturation capacity and mechanical properties are experimentally investigated. Considering the raw material used (fine-grained, dense, high calcium limestone) and the constant maximum calcination temperature at 1000˚C, it is derived that constant heating rates produce more homogeneous and lighter lime binder with enhanced yield and maturation capability (high water retentiveness, stable consistency). The obtained results also indicate that in case of constant heating rates a higher ratio of flexural to compressive strength (ff/fc) can be achieved more rapidly. These properties are essential to mortar quality and application efficiency —with best harmonisation to selection criteria of renders in search of their optimal performance and durability. However, intence constant rates are more likely to give reverse (and misleading) results at lower calcination temperatures in case that a softer raw material or a higher maximum calcination temperature is implemented.
