Influence of Synthetic Fibers on the Flexural Properties of Concrete: Prediction of Toughness as a Function of Volume, Slenderness Ratio and Elastic Modulus of Fibers
The construction industry requires concrete with adequate post-cracking behavior for applications such as tunnels, bridges, and pavements. For this reason, polypropylene macrofibers are used, which are synthetic fibers ...
Recent advances in metal nanoparticles to treat periodontitis
(BioMed Central Ltd., 2023)
The gradual deterioration of the supporting periodontal tissues caused by periodontitis, a chronic multifactorial infammatory disease, is thought to be triggered by the colonization of dysbiotic plaque bioflms in a ...
Experimental Volume Incidence Study and the Relationship of Polypropylene Macrofiber Slenderness to the Mechanical Strengths of Fiber-Reinforced Concretes
An experimental study was conducted to examine the mechanical strengths of concretes with straight high-strength knurled polypropylene macrofibers. Incidences of concrete mechanical strengths were determined for three ...
