... & fracture mechanics fracture energy fracture toughness polymer concrete temperature effects The use of polymer concrete (PC) in the construction industry is becoming more popular owing to its prominent mechanical, thermal and chemical properties, and as such it is considered an advanced...

... residual splitting tensile strength is found to be faster due to the elevated temperature effect. Lastly, in order to reproduce early residual splitting tensile strength, a numerical model is developed and empirical expressions are proposed for engineering application. 27 07 2022 09 12 2022...

... concrete temperature effects tensile properties Ordinary concrete, a typical brittle material, has poor crack resistance and low tensile strength and can easily crack after deformation, which brings follow-up problems to its engineering application. High-ductility concrete (HDC) is an engineering...

... of loading were determined and the effectiveness of bacterial treatments was investigated. Experiments were conducted to determine crack healing, compressive strength, water absorption, ultrasonic pulse velocity and high-temperature effects. In the BM samples, the MICP mechanism repaired cracks about 3.5...
