Fiber-reinforced plastics replacing coated steel in more reinforced-concrete applications.

Concrete has long been used as a building material for its high compressive strength, good durability and low cost. However, its well-known Achilles’ heel is its brittleness and l...

Abstract: The use of fiber reinforced polymer (FRP) bars is one of the alternatives presented in recent studies to prevent the drawbacks related to the steel reinforcement in specific reinforced concrete members. In this work, six reinforced concrete beams were submitt...

A ação de íons cloretos (Cl¯)nas estruturas de concreto além de severo provoca a despassivação do aço muito mais rápida, bem como a corrosão localizada, com surgimento de trincas e desplacamento do concreto. Nas estruturas próximas as áreas litorâneas a ação dos íons c...

A patologia de corrosão da armadura detectadas em estruturas de concreto armado ( lajes, parede estrutural, pilares e vigas), é um processo eletroquímico que provoca a degradação (oxidação) do aço no concreto. Os fatores que afetam este fenômeno estão associados essenc...
