Sand-lime brick

This data set has been modeled according to the European Standard EN 15804+A2 for Sustainable Building. Results are depicted in modules that allow the structured expression of results over the entire life cycle.

Calcium-silicate brick is produced in the following steps: 1. Bearing of lime and sand in silos, primary products are dosed by weight in a mixing ratio of Lime: Sand = 1:12, primary products are mixed 2. Extraction of the quicklime to hydrated lime using water 3. Moulding of the green product in presses 4. Hardening of the blanks at approx. 200°C under water-vapour pressure (about 4 to 8 hours) 5. Cooling of the stones, packaging and shipping In the disposal phase, a mechanical dismantling (excavator) is assumed in module C1. The transport in module C2 to the treatment plant takes place with a truck (50km). In module C3, the material is processed, any reinforcement is fed to a sink (no loads, no credits). A treatment loss of 25% was assumed. This loss is fed to an inert material landfill within Module C3 (average landfill emissions). In Module D, a credit for the net amount of material (excluding reinforcement and treatment losses) for the substitution of natural gravel as backfill material is given.
