Experimental study on basalt textile reinforced concrete under uniaxial tensile loading
HighlightsThe tensile behavior of TRC is related to the number of textile layers.First-crack stress increases with increasing prestress levels.Ultimate tensile strength is slightly influenced by prestress levels.Maintaining the prestress within an appropriate level is important.The tensile behavior of TRC with appropriate prestress level increases with increasing addition of short steel fibers.
AbstractThis study focuses on 24 experimental cases to investigate the influences of textile layers, prestress levels and short steel fibers on the tensile behavior of basalt textile reinforced concrete (TRC). The tensile behavior of basalt TRC is considerably influenced by the number of textile layers. The TRC specimens with one or two textile layers demonstrate no reinforcement efficiency, whereas those arranged with three to five textile layers exhibit pronounced strain-hardening behavior and consequently, prominent enhancement of tensile behavior and optimized cracking patterns. For the prestressed TRC specimens, evident increases in first-crack stress are observed with increasing prestress levels, whereas only a slight influence on ultimate tensile strength can be achieved. Moreover, maintaining the value of the prestress within an appropriate level is an important issue for TRC. Furthermore, the TRC specimens with an appropriate prestress level exhibit increasingly favorable tensile response with the rising volume fraction of short steel fibers.
