The retraction affects the setting process and the useful life of the concrete with the appearance of fissures; in last year's studies and methods have been generated to mitigate and control it with the use of different ...

After several decades of research studies, design rules for fiber reinforced concrete (FRC) are now available for several structural elements. Starting from standard tests, it is possible to determine design parameters and ...

In recent years, the use of steel fibers has increased in Colombia, optimizing structure designs, quality specifications and mechanical behavior. However, the concrete durability and resistance to aggressive environments ...

There is an ever-growing worldwide interest in the use of lignocellulosic fibers as reinforcement in either thermoset (mainly unsaturated polyester) or thermoplastic (mainly polyolefins) composites. However, the wider use ...

In the present work, mechanical properties and failure modes of natural and synthetic fiber reinforced composite sandwich panels under three point bending were studied. Analytical models were developed in order to predict ...

Recent works about the mechanical and fracture behavior of natural fiber reinforced polypropylene composites were presented, focusing on the deformation characteristics and the fracture and failure mechanisms exhibited by ...
