CLS Rck15 S4 X0 D25 CEM II B-LL 42,5 R CAM CL02

The concrete studied is CLS Rck15 S4 X0 D25 CEM II B-LL 42,5 R CAM CL02.

For the evaluation of impact, the declared unit of concrete is 1 m3. The reference period for the collected data is the year 2023. The total amount of concrete made, in the considered period, is <100 m3. According to EN 15804:2012+A2:2019/AC:2021 the study spans from “cradle to gate with options”, with the modules: A1, A2, A3, B1, B2, B3, B4, B5, B6, B7, C1, C2, C3, C4 and D. Exclusion of input and output data, i.e. “cut off criteria”, is fixed at 1%, in term of mass, energy and environmental relevance. Thus, a process can be neglected if its contribution is minor to 1% of the total mass, primary energy and total impact. However, all processes for which data are available are considered, even though with a contribution minor than 1%.

The production of concrete is modelled by primary data collected in TARANTO (TA) is the production site for the above said considered reference period. Allocation is avoided, whenever possible, by dividing the system into sub-systems. When allocation cannot be avoided, mass allocation is applied. For the modeling of waste, the “Polluter pays principle” is applied.
