Conventional glass fiber-reinforced concrete (GFRC) has wide applications in high-rise buildings, bridges, and renovation works. In this study, ultra-high-strength fiber reinforced (UHS-GFRC) mixtures were developed to minimize the size of structural members. The percentage was varied as 0%, 0.03%, 0.06%, 0.09%, 0.12%. investigation, ten beams cast tested, with two span-to-effective-depth (a/d)...

In this study, filler and silica fume were substituted by Liquid crystal display glass powder (LCDGP) nanosilica, respectively, to improve the performance of ultra-high- fiber-reinforced concrete. addition, surface steel fiber was modified with ethylenediaminetetraacetic acid (EDTA) solution interfacial friction between Ultra-high-performanceconcrete (UHPC) matrix. Both LCDGP nanosilica reacted...

The addition of steel fibers into concrete improves the postcracking tensile strength of hardened concrete and hence significantly enhances the shear strength of reinforced concrete reinforced concrete beams. However, developing an accurate model for predicting the shear strength of steel fiber reinforced concrete (SFRC) beams is a challenging task as there are several parameters such as the co...

Since the early 1930s, the process of melting glass and subsequently forming fibers, in particular discontinuous fiber glass or continuous glass filaments, evolved into commercial-scale manufacturing. Most commonly, a direct melt process is applied. Thereby, the several raw materials were mixed, fed into a furnace, melted and forwarded to the fiber-forming units. Here, the filaments are formed ...

Abstract. Today’s world is more concerned about the preservation of natural sources. Consumption less amount resources in construction activities equally important as energy saving after construction. To combine both aspects, one such thing tried this work translucent concrete. As everyone knows, concrete termed traditional material for a building. The property hidden light emission. When hits ...
