Reinforced Lime Concrete with FRP: An Alternative in the Restoration of Architectural Heritage

What is it about?

Reinforced concrete has been the material mainly used in the repair of traditional structures of historic buildings. However, since the end of the 20th century, it began to question its use, especially for damages arising from corrosion of steel. An alternative is lime concrete reinforced with Glass Fiber Reinforced Polymer (GFRP) bars. Current lime concrete provides a high compressive strength and prevent problems such as cement alkalinity. GFRP bars provide the necessary tensile strength. Its modulus of elasticity and adhesion, improved by various mechanisms, allows good compatibility with concrete lime. Mechanical characteristics of the mixture are studied together to withstand the tensions and compressions in historic buildings. This new material is progressively replacing to Portland cement in the restoration of architectural heritage
