To investigate the influence of alkali-resistant glass fiber on dynamic mechanical properties and microstructure slag cement mortar (SCM), five SCM blocks with different volumes (0%, 0.25%, 0.5%, 0.75%, 1%) were prepared. A split Hopkinson pressure bar (SHPB) test device a diameter Φ50 mm was used to impact compression under loading pressures. In this way, stress–strain curve average strain rat...

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 ...

Tm-doped alkali germanate glass is investigated for use as a laser material. Spectroscopic investigations of bulk Tm-doped germanate glass are reported for the absorption, emission and luminescence decay. Tm:germanate shows promise as a fiber laser when pumped with 0.792 μm diodes because of low phonon energies. Spectroscopic analysis indicates low nonradiative quenching and pulsed laser perfor...

Polymeric coatings are widely used to enhance the load bearing capacity and chemical durability of alkali-resistant glass (AR-glass) textile in cement-based composites. The contact zone between coated yarns concrete matrix plays a major role enable stress transfer has still be improved for full exploitation mechanical behavior composite. As new approach, this paper studies how addition nanoclay...

Concrete is most widely used construction material in the world. Fiber reinforced concrete (FRC) is a concrete in which small and discontinuous fibers are dispersed uniformly. The fibers used in FRC may be of different materials like steel, G.I., carbon, glass, aramid, asbestos, polypropylene, jute etc. The addition of these fibers into concrete mass can dramatically increase the compressive st...
