The article examines the technical characteristics of glass fiber reinforced concrete based on experimental research and selection optimal composition concrete. When selecting composition, various technologies for introducing fibers, percentage fibers introduced, sand used were analyzed. obtained results allow us to determine effectiveness use structures in reconstruction buildings structures. ...

the creep behavior of basalt fiber reinforced epoxy (bfre) and glass fiber reinforced epoxy (gfre) composites was studied through tensile testing at high temperature. to study the effect of reinforcing epoxy, the micro glass powder (mgp) was added at various volume percentage into the epoxy resin in bfre composites. the initial strain for all the specimens were evaluated and compared with each ...

There have been great developments in the area of civil engineering in the recent few decades and among these, construction and material innovation are quite prominent. Steel-concrete composite construction has emerged as one of the fastest methods of construction. Even though considerable research efforts on conventional reinforced concrete columns have been executed prior to now, concrete fil...

background: glass and quartz fiber posts are used in restoration of structurally compromised roots. accessory fiber posts are recently introduced to enhance the fiber post adaptation. this study evaluated the effectiveness of glass versus quartz accessory fiber posts. materials and methods: in this experimental study, 40 mandibular premolar roots with similar dimension (radius of 3.5 ± 0.2 mm a...

This work addresses the assessment of the electromagnetic disturbance induced by a composite barrier—fencing airport structures—to radio-communication electromagnetic waves. The barrier is composed of glass fiber reinforced polymer GFRP tubular elements installed into a concrete base. Based on the electromagnetic properties of constituent materials, numerical analyses describing the electromagn...
