SMAR 2024 – 7th International Conference on Smart Monitoring, Assessment and Rehabilitation of Civil Structures Life Cycle Sustainability Assessment of industrial flooring Federica Russo a , Gabriella Maselli a , Antonio Nesticò a, * a Department of Civil Engineering, University of Salerno, Via Giovanni Paolo II, 132 - 84084 Fisciano (SA), Italy Abstract The use of fibre-reinforced concrete for industrial floors makes it possible to significantly contain the phenomenon of crack formation and propagation, which is the cause of degradation in traditional concrete floors. In fact, the structural fibres in place of the welded mesh form a homogeneous and omnidirectional reinforcement throughout the screed layer and, as a result, increase the load-bearing capacity of the structure due to a high residual tensile strength after cracking. This study aims to establish a methodological framework useful for comparing the environmental and economic performance of two alternative technological solutions for large span industrial floors: on the one hand, the traditional concrete solution; on the other hand, the innovative fiber-reinforced concrete solution, specifically tensofloor with post-tensioned reinforcement. To this end, an evaluation approach based on the integrated use of Life Cycle Costing (LCC) and Life Cycle Assessment (LCA) is proposed. The methodology makes it possible to assess (i) the financial sustainability of technological solutions by considering the costs related to the entire life cycle, from implementation to disposal; (ii) the environmental impacts generated by design alternatives in a cradle-to-grave perspective.
