This research paper compares the thermal conductivity and thermal expansion coefficients of glass fiber reinforced epoxy composite laminates (GFRP laminates) made using the Hand layup technique. The composite laminates were fabricated by filling with varying concentrations of fly ash, stone powder, aluminium oxide (Al2O3), magnesium hydroxide (Mg (OH)2), Silicon carbide particles(SiC) and hemat...

In this paper, a comprehensive experimental study was conducted to investigate the bond performance of sand-coated glass fiber reinforced polymer (GFRP) bars embedded in normal concrete with different bar sizes and regions beams following regulation Rilem beam. The achieved results are compared analytical equations presented by current codes reputable recent research using average strength free...

Investigations on flexural and tensile properties of GFRP laminates influenced by stainless steel wire reinforcement were carried out as a novel approach. Plain GFRP laminates and GFRP laminates reinforced with stainless steel wires at different depth with various pitch distances were fabricated by hand layup method. The composite specimens reinforced with steel wires were exposed to low freque...

Reinforced concrete (RC) structures may be subjected to an increase in load, severe environmental attack, and other factors that lead deterioration. Strengthening/repair techniques are typically used upgrade the strength or enhance durability, which extends service life of structures. In current study, behavior reinforced beam strengthening by UHPC layer with/without construction joints were in...

This study investigates the behavior of three concrete beams reinforced with steel and GFRP bars under fire exposure. The tests were conducted including one control steel-reinforced (RC) beam two GFRP-RC beams. exposed to according standard curve ISO 834 for 3 h. investigation parameters included reinforcement types (i.e., bars) diameter bars. Based on experimental results, during exposure, def...

BACKGROUND AND PURPOSE 6R-L-erythro-5,6,7,8-tetrahydrobiopterin (BH4 ) is an essential cofactor for nitric oxide biosynthesis. Substantial clinical evidence indicates that intravenous BH4 restores vascular function in patients. Unfortunately, oral BH4 has limited efficacy. Therefore, orally bioavailable pharmacological activators of endogenous BH4 biosynthesis hold significant therapeutic poten...

Fiber reinforced polymer materials are continuing to show great promise for using strengthening reinforced concrete structures. These materials are an excellent option for use as external reinforcing, because of their light weight, resistant to corrosion and high strength. The main aim of this study is to investigate the flexural characteristic of RC beams using GFRP sheets and strips. This pap...

Glass fibre reinforced polymer (GFRP) profiles are finding increasing applications in civil engineering structures, owing to the several advantages they offer over traditional materials. However, due to the combustible nature of their polymer matrix, there are well-founded concerns about their behaviour at elevated temperature and under exposure to fire. These concerns are hindering the widespr...

A novel real-time radar NDE technique for the in-depth inspection of glass fiber reinforced polymer (GFRP)retrofitted concrete columns is proposed. In this technique, continuous wave radar signals are transmitted in the far-field region (distant inspection), and reflected signals are collected by the same signal transmitter. Collected radar signals are processed by tomographic reconstruction me...
