Sustainable Assessment of Concrete Repairs through Life Cycle Assessment (LCA) and Life Cycle Cost Analysis (LCCA)

Nowadays, a vast number of concrete structures are approaching the end their expected service life. The need for maintenance and repair is high due to continued deterioration existing building inventory infrastructure, resulting in large near future. Reinforcement corrosion most important mechanism, causing (i) severe damage (cracking along reinforcement spalling cover concrete) (ii) loss steel section. Therefore, appropriate techniques main focus this review paper. With European transition towards circular economy with sustainable development goals mind, it also consider environmental impact technical requirements life cycle cost. In order improve sustainability repairs over cycle, assessment (LCA) cost analysis (LCCA) should be applied. However, more research efforts needed field further refinement. This literature tries adress by compiling knowledge gaps state-of-the-art. A comprehensive survey about through LCA LCCA performed showed potential investigation. Additionally, was noticed that many differences present between studies considering and/or LCCA, namely, considered structures, causes, (iii) techniques, (iv) estimated spans, (v) methods, (vi) (LCIA) etc. case specificity, mutual comparison challenging.
