Abstract Concrete is one of the most extensively utilized building materials that can be produced, and has potential to release a significant quantity CO 2 into environment. In this research, through studying lightweight (LW) concrete, attempts are made produce environmentally friendly LW concrete with high strength using nanosilica rather than part cement waste glass powder instead aggregates....

Advanced composite materials used in high-tech fields are widely reinforced with carbon fibers. One of the growing application areas for fibers is their composites which to replace metallic automotive parts. This reduces footprint through weight reduction, a strategy pursued globally reduce environmental impacts passenger vehicles. In this study, we assess reinforcement potential recycled polyp...

INTRODUCTION Adhesions to mesh/tacks in laparoscopic ventral hernia repair are often cited as reasons not to adopt its evidence-based superiority over conventional open methods. This pilot study assessed the occurrence of adhesions to full-sized Polypropylene and Gore-tex DualMesh Plus meshes and the possibility for adhesion prevention using fibrin sealant. METHODS Two 10-cm to 15-cm pieces ...

Recycled aggregate concrete has received increasing attention owing to its broad development prospects in recent years. This study discusses the enhancement mechanism of various fibers on mechanical properties, high-temperature resistance, and freeze–thaw cycle resistance recycled concrete. It reviews effects fiber types content strength, failure state, concrete’s high low temperatures. The res...
