Lime has been an important component of mortars for over 2000 years. The characteristics of hydrated lime provide unique benefits in masonry applications that distinguish cement-lime mortars from other masonry mortar materials. Major benefits include: Flexural bond strength Cement and Type S Hydrated Lime mortars have been shown to have high levels of flexural bond strength.
The predominant raw material for the cement in concrete is limestone, the most abundant mineral on earth. Concrete can also be made with fly ash, slag cement, and silica fume, all waste byproducts from power plants, steel mills, and other manufacturing facilities. Durability.
Lime mortar does not adhere as strongly to masonry as Portland cement. This is an advantage with softer types of masonry, where use of cement in many cases eventually results in cement pulling away some masonry material when it reaches the end of its life.
Raw materials used for manufacturing of Portland cement are found naturally in the earth's crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron. Both are found as clay or shale.
