| Technology description including background system | Concretes and mortars are a mixture of cement, water and aggregates (e.g. sand, gravel, flint, blast furnace slag) and, when necessary, additives such as condensers, retarding agents or air-entraining agents. Cement and water form the cement paste binds the grains of stone forming a hard stone. The concrete's properties can be altered by using different structutres and grains of stone. The data represent typical values for the production of ready-mix concrete in Germany. 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. |
