Experimental study on flexural behavior of prestressed and non-prestressed textile reinforced concrete plates

The application of prestressing steel is restricted in highly corrosive environment area due to corrosion of prestressing steel, which leads to reduction in strength and it may cause sudden failure. Carbon textile is considered as an alternate material due to its corrosive resistance property, high tensile strength and perfectly elastic. In this study, an experimental investigation was carried out to study the flexural behavior of prestressed and non-prestressed carbon textile reinforced concrete plates. This study also focuses on the influences of textile reinforcement ratios, prestress grades on the flexural behavior of carbon textile reinforced concrete (TRC). Fifteen precast TRC plates were tested, of which six were prestressed to various levels with carbon textile. The obtained results show that prestressing of textile reinforcement results in a higher load bearing capacity, stiffness and crack resistance for TRC plates. | Experimental study on flexural behavior of prestressed and non-prestressed textile reinforced concrete plates Transport and Communications Science Journal, Vol. 71, Issue 1 (01/2020), 37-45 Transport and Communications Science Journal EXPERIMENTAL STUDY ON FLEXURAL BEHAVIOR OF PRESTRESSED AND NON-PRESTRESSED TEXTILE REINFORCED CONCRETE PLATES Nguyen Huy Cuong1*, Ngo Dang Quang1 1 University of Transport and Communications, No 3 Cau Giay Street, Hanoi, Vietnam.
