In comparison with fiber-reinforced polymer (FRP) composite, the textile-reinforced concrete (TRC) presents stability in mechanical performance at elevated temperatures thanks to a thermal protection layer by the cementitious matrix. This paper presents the experimental characterization and analytical modeling for fire performance of carbon TRC under the thermomechanical regime at constant tensile force.

Strengthening of reinforced concrete (RC) columns is needed when the actual load-carrying capacity of the columns does not reach the required level due to either structural deterioration or increasing acting loads. This experimental study aims to evaluate the strengthening effect on the eccentrically-compressed RC columns using Carbon fiber reinforced polymer (CFRP) sheets, that confine around the column cross-section.

Engineered cementitious composite (ECC) creates many potential civil engineering applications due to its outstanding ultimate tensile strain capacity (normally exceeding 2%) compared to conventional concrete and fiber reinforced concrete. The high tensile ductility of ECC is mainly influenced by fiber characteristics.

natural fiber for the construction of hybrid bio-composites. In the current research project, a thorough analysis of the use of soy-PF resin for the creation of composites reinforced with jute was conducted. A novel and practical cutlery material was created after the mechanical properties were evaluated and optimized. In order to study the value addition of these newly proposed biocomposite materials as an ecological alternative in terms of natural resources versus synthetic resources, variables such as hardness, cytotoxicity, and degrading qualities of composites were also explored.

Steel fiber reinforced concrete (SFRC) is a multiple-composite material developed during the early 1970s. In SFRC, short steel fibers are randomly distributed in concrete. Steel fibers can prevent the development of micro-cracks inside the concrete and reduce the expansion and development of the macro-cracks, thus enhance mechanical performance of SFRC. However, there is lack of studies on the influence of flowability of fresh SFRC on the steel fiber distribution patterns and mechanical properties of hardened SFRC.
