Aims and Objective Denture fractures are a common problem in clinical practice. Despite the use of different reinforcement materials (metal wires, metal plates, and various types of fibers) for denture repairs, recurrent fractures are still common. The purpose of this study was to compare the maximum flexural loads of the heat-polymerized denture base resin when repaired with autopolymerizing r...

The corrosion resistance of fly ash-based geopolymer structural concrete (GPC), with or without fibers, was investigated in a simulated marine environment, and compared that ordinary Portland cement concrete. behavior is studied through an electrochemical method for inducing accelerated corrosion. fiber reinforced beam specimens contained polyolefin fibers the amounts 0.1%, 0.3%, 0.5% by volume...

Abstract Fiber reinforced concrete (FRC) is being widely used as the structural material owing to its superior engineering properties. From past, it was understood that Reinforced Concrete had been proved be well performing over time under different practical situations. Fibers enhance mechanical properties of and in turn change structbehaviouravior. It observed high strength fibers are availab...

An experimental test was performed to study the bond behavior between steel rebar and concrete reinforced by polyvinyl alcohol (PVA) fibers. Twenty specimens were prepared subjected pull-out test. Four different fiber volume contents (0%, 0.2%, 0.4%, 0.6%) considered with strength grade of C35 designed in present study. The effects PVA fibers, diameter, cover depth on clarified. fibers mechanic...

Sustainable development is a major issue confronting society today. Cement, constituent of concrete, key component any infrastructure development. The drawback cement production that it involves the emission CO2, predominant greenhouse gas causing global warming. geopolymers has resulted in decrease production, as well reduction CO2 emissions. During mass concrete construction very large struct...

Adding steel fibers to a concrete matrix enhances the shear capacity of reinforced beams. A comprehensive understanding this phenomenon is essential evaluate engineering designs accurately. The Steel Fiber Reinforced Concrete (SFRC) beams affected by many parameters, such as ratio span effective depth SFRC beam, compressive strength concrete, longitudinal reinforcement ratio, volume fraction, a...

In this study, we applied an electrospinning (ES) method, which is mainly employed in the textile industry, to the field of pharmaceuticals. We developed and modified an ES instrument and then utilized it to produce methacrylic acid copolymer S (MAC) nano-fibers to prepare tablets. By attaching a conductor rod made from stainless steel to the central part of the nano-fiber-collection plate of t...

SIFCON is characterized as a construction material of high ductility and very strength. It suitable for concrete structures used special applications. However, the density much higher than that Fiber Reinforced Concrete (FRC) due to need large amount high-density steel fibers. This work examines split tensile behavior modified weight slurry infiltrated fiber utilizing mixture two types fibers, ...

Many factors affect the torsional behavior of reinforced concrete beams, such as strength, section dimensions, aspect ratio and cover. Improvements in RC members had led researchers to investigate effect additional steel fibers, reinforcement arrangement. Based on above, there is a gap previous studies taking distribution stirrups with longitudinal fibers. Twenty-six beams 250 mm wide, high 115...

With increasing construction activity and concrete consumption globally, the economic, environmental, social impacts of human activities continue to increase rapidly. Therefore, it is imperative assess choice each structure structural component from a sustainability-based perspective. In this study, such multi-criteria decision-making approach using MIVES method applied grouped continuous fligh...
