Degradation of basalt based reinforcement elements in salt solution

Popis výsledku v původním jazyce

Basalt fibers and their products (fabrics, mesh, ropes etc.) are currently widely used as reinforcing elements in composites based on thermosetting plastics. Another possible application of basalt fibers lies in civil engineering where these fibers may be used in concrete as alternative to the conventional steel reinforcement. The basalt reinforcement can be realized in two ways: a) dispersed short basalt fibers (alternative to steel wires); b) basalt fiber reinforced plastic (BFRP) bars (alternative to steel rebars). As the “plastic” component, epoxy or vinyl ester resin is used. The primary driving force for replacement of steel reinforcing elements in concrete by another material (e.g. basalt fibers) is the steel sensitivity to electrochemical corrosion, which is frequently determining the lifetime of concrete structure. For the obvious reasons, basalt elements are not suffering from electrochemical corrosion, but it does not mean that they are completely corrosion-resistant. The present paper aims to contribute to the knowledge on corrosion behavior of BFRP bars in Simulated Sea Water (SSW). The experimental program consisted in exposing of BFRP bars to SSW and measurement of its tensile strength in time. It can be concluded that the strength controlling point is interlaminar shear of bars which is reduced by ongoing hydrolysis of epoxy resin during the bars exposure to Simulated Sea Water.
