Consolidated modified MODA template and LCA formalism

These deliverables are aimed at updating the MODA template, taking also into account the Life Cycle Assessment (LCA) analysis and results, for the evaluation of the durability and sustainability performances of the proposed materials. The durability performance will be investigated through modeling activities, based on the investigation of the: 1) aging phenomena of UHDC, as modified by functionalizing constituents, including corrosion of reinforcement; 2) crack self-sealing/healing processes in UHDCs as also engineered through functionalizing constituents. Instead, the environmental performance will be analyzed through the: 3) Life Cycle Assessment methodology.

Moreover, in this deliverable an overview of the LCA will be also reported focusing on the first phase of the methodology: the Goal and Scope Definition phase, according to the ILCD Handbook and the ISO 14040 and 14044 standards. - II version M37: the second version of the deliverable will present the preliminary results of the LCA of the selected UHDC solutions (materials and components) using, for the Life Cycle Inventory phase, data and feedback coming from the other WPs (i.e. WP4, WP7 etc.). - III version M42: the final version of the deliverable will update and validate the results of the LCA of UHPC.
