| Use advice for data set | This dataset refers to the production of 1 kg calcium sulfate screed. The bulk density is 1500 kg/m³. The compressive strength depends on the specific construction. The dataset can be used approximately for the estimation of bulk densities of 1400 - 1600 kg. 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 | Calcium sulfate screed is used as leveling and base layer in the floor structure. Frequently, calcium sulfate screed is used as floating screed, which allows seamless laying without additional effort for compacting or smoothing. | ||

| Technological representativeness | |||
| Technology description including background system | Calcium sulfate screed is a mixture of various binding agents, aggregates and additives. The finely ground aggregates and the binding agents have a relevant impact on the LCA. Both dry and fresh screed were considered (50/50 mix), with only the dry matter being balanced for the LCA. In the disposal phase, a manual dismantling (no loads) is assumed in module C1. The transport in module C2 to the landfill site takes place with a truck (50km). In C3, if relevant, a packaging with PE foil is taken into account (for example, for mineral fiber products. 0.0125 kg foil per kg of discarded material). In module C4 the average landfill emissions corresponding to the product (reference country Germany) are shown. The use of landfill gas is not taken into account. | ||
