Effect of the time development of physical and chemical degradation of basalt-based reinforcement on its applicability in cement composites
Original language description
Basalt fibers based reinforcing elements for concrete structures (Basalt Fiber Reinforced Polymer bars (BFRP), chopped basalt fibers) are supposed to be more corrosion resistant than the common steel rebars and wires, especially in the marine environment. Mild steel, used for production of conventional concrete reinforcing elements, is well-known for its corrosion resistance in the basic environment provided by cementitious concrete matrix. As the pH of concrete goes down in time due to carbonation and other processes, the steel corrosion is activated. The chloride anion (marine environment) is also acting as mild steel corrosion activator. On the other hand, the basalt fibers are supposed to be resistant to the chloride activation. Concerning the pH effect, basalt is sensitive to the both acid and alkaline environment where its dissolution may take place. It means that it should not be vulnerable to the pH decrease as the mild steel does. The present paper aims to test how the lower pH influences the performance of basalt fibers in cementitious matrix.
