This research investigates and compares the behavior of conventional self-compacting concrete (SCC) with a novel glass fiber reinforced under tension. Self-compacting is known for its ability to flow fill formwork without needing external vibration. Adding reinforcement offers potential improvements in tensile strength cracking resistance. To compare concrete's split concrete. In this experimen...

Different glasses suitable for temperature sensing in the fiber optic sensors were studied in this article. The phase changes for eight different glass materials were calculated and results were compared. Our results showed that extra dense flint glass is the most sensitive one, while pure silica results in the lowest phase change. In another study the effect of wavelength on the phase variatio...

the value of the permeability in fluid flow through porous media is important for process investigation. in low reynolds number, the classic darcy’s law is suitable for simulation of fluid flow. in this paper, an experimental study for evaluation of preformed fiber permeability has been done. also, the deviations from the classical darcy law by experimental and numerical simulation of the navie...

The flexural behaviour of concrete containing Foamed glass as partial replacement of coarse aggregate is investigated. The coarse aggregate was replaced with 0%, 25%, 50%, 75% and 100% Foamed glass. All other constituents were maintained the same. Reinforced concrete beams were cast using 2 bars of 8mm in diameter in the tensile zone. The density and compressive strength of concrete decreased a...

in the present research work, the flexural modulus and strength of glass fiber-epoxy resin and carbon fiber-epoxy resin composites have been enhanced through fiber tension during curing of the polymeric resin. this study showed that the tension applied on the fibers increased the flexural modulus of the glass-epoxy composites up to 12% and the flexural strength up to 19%. the flexural modulus a...

In order to study the basic mechanical properties of basalt fiber reinforced recycled aggregate concrete, the concrete mix ratio, the length and the volume mixing ratio of chopped basalt fiber yarn are designed for changing factors. A total of 324 specimens have been completed for this investigation. The compressive strength, splitting tensile strength, elastic modulus and axial compressive str...

This paper discusses the potential use of multi-walled carbon nanotubes (MWCNTs) to improve the mechanical properties of short glass fiber composites. Two methods to incorporate MWCNTs in short glass fiber composite fabrication were examined. First, Carboxylic-functionalized MWCNTs were dispersed in a silane fiber sizing material and then were allowed to bond to the surface of glass fibers. Sec...

statement of problem: microleakage is one of the most important problems in composite restorations. one way to reduce the microleakage is decreasing the total amount of resin by insertion of fibers in composite restorations. objectives: this study aimed to compare the microleakage of silorane and methacrylate-based composites (a nanohybrid) in class ii restorations with gingival margins on the ...

Repairing deteriorated concrete bridge piers using externally wrapped FRP (fiber reinforced polymer) composites has been proven as an effective approach. This technique has also been applied to low-rise building structures. Failures in FRP-wrapped concrete structures may occur by flexural failures of critical sections or by debonding of FRP plate from the concrete substrate. Debonding in the FR...

Over the last two decades fiber-reinforced polymer (FRP) rods have emerged as one of the most promising and affordable solutions to the corrosion problems of steel reinforcement in structural concrete. The application of FRP rods in new or damaged structures requires the development of design equations that must take into account the mechanical properties and the durability properties of FRP pr...
