Executive Summary : | Textile reinforced concrete (TRC) is a high-performance cement-based composite reinforced with glass, carbon, basalt, and aramid textiles for various applications. It has been used in structural and non-structural structures, enhancing tensile strength, durability, and thermal efficiency. The type of fiber material used and the density of textile in warp and weft directions influence flexural toughness. TRC is a relatively new building material, and investigating its interaction with core materials is an upcoming research field. TRC sandwich beams are used as skins, and it is crucial to study the behavior of TRC sandwich elements subjected to elevated temperatures. Few studies have focused on the effect of elevated temperatures on TRC with AR Glass, E-Glass, carbon, and basalt fiber reinforcement. High temperatures can lead to deterioration of TRC composites, with some enhancing tensile and bond strength up to 150-200°C. However, high temperatures can also lead to textile degradation and degradation of the textile-to-mortar interface. Aramid fibers are characterized by high melt temperature, excellent thermal stability, flame resistance, and low solubility in inorganic solutions. This research aims to develop textile reinforced concrete sandwich beams/panels with aramid fiber as reinforcement and calcium silicate board as core material, focusing on their performance and thermal behavior. Nationally, research on TRC sandwich panels is scarce, and there is a lack of studies on the heat transfer performance, particularly the combustion performance, of TRC sandwich panels with Aramid fiber reinforcement and calcium silicate board as core material. Experimental research is needed to disclose the fire resistance behavior of TRC sandwich panels/beams with Aramid fiber as reinforcement and calcium silicate board as core material. |
