The ancient Romans used lime in building and road construction, uses which continue to the present day. Lime has the following advantages over conventional cements. Type S lime is not considered reliable as a pure binder in mortar due to high burning temperatures during production. On the other hand, carbonation will no longer only take place from air, but also in the presence of water: this is why some of these lime can be used under water. The S in type S stands for special which distinguishes it from Type N hydrated lime where the N stands for normal. Selenitic lime, also known as Scotts' cement after Henry Young Darracott Scott is a cement of grey chalk or similar lime, such as in the Lias Group, with about 5% added gypsum plaster (calcined gypsum). The goal is to democratize the concept of econology, for the benefit of current and future generations ... Econology aims to show that it is possible to reconcile economy, ecology and environment.  Natural hydraulic lime (NHL) is made from a limestone which naturally contains some clay.  Dolomitic lime has a high magnesium content of 35-46% magnesium carbonate (ASTM C 59-91). After processing, the carbonation process begins. Key words: construction, mortar, wall, cement, eco-construction, moisture, benefits. , Heather Hartshorn, "Dolomitic Lime Mortars: Carbonation Complications and Susceptibility to Acidic Sulfates" Thesis. BUILDING LIME TERMINOLOGY Â The lime cycle for dolomitic and magnesium lime is not well understood but more complex because the magnesium compounds also slake to periclase which slake more slowly than calcium oxide and when hydrated produce several other compounds thus these limes contain inclusions of portlandite, brucite, magnesite, and other magnesium hydroxycarbonate compounds. In construction, the uses of lime are multiple and above all, it is suitable for almost all types of media, whether straw, stone, terracotta, mud or other. Magnesium lime contains more than 5% magnesium oxide (BS 6100) or 5-35% magnesium carbonate (ASTM C 59-91). " The term Type S originated in 1946 in ASTM C 207 Hydrated Lime for Masonry Purposes. Silica combines with limestone during calcination and gives more resistance to the mortar.  The conditions and compounds present during each step of the lime cycle have a strong influence of the end product, thus the complex and varied physical nature of lime products.
