| Abstract Scope |
Lime, used since ancient times, remains relevant in civil construction because of its adhesion, durability, and compatibility properties. In the form of an aqueous suspension, known as milk of lime, it plays an essential role in the formulation of mortars. This study evaluated the behavior of coating mortars with a ratio of 1:1:6 (cement:lime:sand), using hydrated lime powder in a proportion of 100% in relation to the cement mass, and in proportions of 100%, 75%, and 50%, previously hydrated in water. Lime was characterized using SEM-EDS and XRD analyses to determine its morphology and mineralogical composition. The mortars were subjected to tests in the fresh state (consistency, density, entrained air content, and water retention) and hardened state (flexural tensile and compressive strength). The results indicate that the reduction of lime solubilized in water can contribute to cement hydration, promoting more economical and sustainable alternatives. |
