Hybrid Fiber Reinforced Concrete Containing Pumice and ...

ABSTRACT: Fiber reinforced concrete (FRC) has been widely used due to its advantages over plain concrete such as high energy absorption, post cracking behaviour, flexural and impact strength and arresting shrinkage cracks. But there is a weak zone between fibers and paste in fiber reinforced concretes and this weak zone is full of porosity, especially in hybrid fiber reinforced concretes. So ...

Design and Field Evaluation of Hybrid FRP/Reinforced ...

05/09/2009  Fiber-reinforced polymers offer several advantages over conventional construction materials but are also faced with several challenges. These include increased first cost, relatively low stiffness, and a lack of field experience. To address these challenges and to advance the state of the art, a hybrid fiber reinforced polymer/reinforced concrete bridge was designed and constructed in Texas ...

Synthetic Fiber Reinforced Concrete - IJERT

Fiber reinforced concrete (FRC) is concrete mix with a fibrous material to increase its structural integrity. It contains short discrete fibers which are uniformly distributed and randomly oriented. Fibers include steel fibers, glass fibers, synthetic fibers and natural fibers- each of which lend varying properties to the concrete. Fibers arrest the crack and also restrict the development of ...
