| Technology description including background system | The light concrete mix is produced in a mixer from washed pumice and exactly dosed quantities of water and bonding agents. The mixture arrives in the filling chest of the stone moulding machine which feeds the charging car. The charging car then goes over to the metallic mould (which is set on a board) and fills it up. The stone moulds contain enough cores (for the particular type of stone) for grooves or chambers. With extra loading and vibration the mixture is compacted and the stone is pushed out of the mould. The stones on the underlying boards are taken to a high bay racking where they set for 24 to 36 hours. They are stored for 6 weeks, longer than the required standard of 28 days, in the yard. 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. |
