Polymer modified concrete impact on the durability of infrastructure exposed to chloride environments

A limited number of studies are available on the impact polymer modified concrete corrosion effect Reinforced Concrete (RC) structures, such as bridges exposed to maritime environments or de-icing salts. The aim this research was analyse influence polymers mechanical and durability properties concrete. Seven types recyclable thermoplastic PCL, Polymorph, LDPE/EVA granular, powder, GPE, N-228 TPE were used fine aggregate replacement (3 5%). molecular weight structure, size, shape surface texture fresh hardened evaluated. All concretes designed for a compressive strength higher than 50 MPa. results show that makes suitable conventional reinforced manually compacted heavily sections with vibrations. Adding granular powder form lead 2–15% increase. For most studied, their preventing water migration via capillarity seems occurr 2–3 days after exposing water. substitution natural aggregates some reduction chloride ion into samples, indicating them stop free chlorides inside 5% leads restricted movement coefficient decreased by 64% in comparison plain
