Lime - hydraulic (lime production - hydraulic)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. The product "lime hydraulic" represents a binder which is produced from marl lime or calcareous marl by calcination below the sintering point (temperature of calcination: around 1050ºC max. 1200ºC). The basic material must have a share of 65 to 75% in calcium carbonate. The calcined hydraulic lime is slaked and milled. To regulate the cementation gypsum is added during the grinding process. Compared to cement the SiO2 content of hydraulic lime is varying strongly (5 - 30%). No content of Alit (tricalcium silicate) a high content of Belit (dicalcium silicate) and a higher amount of lime (>5%) are typical for hydraulic lime. Further significant differences to cement are better working properties but worse hydraulic characteristics and lower strength (1 - 5 N/mm2). It is the main raw material for the production of masonry cement or plastering mortar. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
