| Use advice for data set | This dataset refers to 1 m³ unfilled pumice stone (hollow block) for the production of masonry. Bulk density 900 kg/m³, thermal conductivity 0,34 - 0,37 W/mK. Compressive strength 4 N/mm². The data set can be used for the approximate estimation of other stone bulk densities of 500 - 1300 kg/m³. The data set represents a cradle to gate inventory. It can be used to characterise the supply chain situation of the respective commodity in a representative manner. Combination with individual unit processes using this commodity enables the generation of user-specific (product) LCAs. | ||
| Technical purpose of product or process | Pumice stones are usually used in the outer wall area using thin-bed mortar (indoor use is also possible). The masonry must be protected from weather conditions by additional layers (such as plaster and paint). | ||

| Technological representativeness | |||
| Technology description including background system | Main raw materials are pumice and cement. These are mixed with water, introduced into molds, compacted and then stored for curing. The LCA results are dominated by the use of cement. 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. | ||
