Stress-based crack criterion as a basis for prevention of through-cracks in concrete structures at early ages This contribution deals with the results of a recent study on stress development and risk of cracking in plain hardening concrete. The experiments are performed in a Temperature Stress Testi...
Table 1 Summary of governing equations for various damage-based traction–separation laws for concrete and other quasibrittle materials (Planas et al.2018) Full size table In a recent internal report, the authors classified a representative subset of the existing cohesive models according to the schem...
High strength concrete using silica fume is prone to plastic shrinkage cracking in dry and windy conditions. Addition of fibres is known to restrict the gr... A Sivakumar,M Santhanam - 《Cement & Concrete Composites》 被引量: 145发表: 2007年 Resistance to stress corrosion cracking of unidirecti...
Concrete cracking is regarded as one of the foremost factors posing a long-term safety threat to the durability of structures. Recently, microbially induced calcium carbonate precipitation (MICP) has been gradually applied in the field of concrete crack repair, which aims to achieve the repair of...
However, its stress–strain response is substantially different to that of prototype concrete when entering the nonlinear post-cracking regime, while it also exhibits a dissimilarly larger tensile strength. In order to investigate the applicability of the proposed similitude laws for reinforced concrete ...
Due to the opening the RC flat plates always need to be strengthened.The existence of the opening on the flat plates will lower the ultimate capacity and the rigidity.The stress concentration of the concrete taking place at the surrounding of the opening especially at the corner often causes th...
The stress corrosion and hydrogen embrittlement behavior of AISI 1080 steel employed in concrete prestressing tendons was studied with different experimental techniques. A simulated concrete pore solution, with and without contaminants such as chloride, sulfate and thiocyanate ions was used. For comparison...
Secondly, the stiffness reduction factor of concrete in the model was calculated according to the existing experimental data, and the engineering formula of the steel corrosion degree was established, which was related to the surface crack width of reinforced concrete. Moreover, the experiments of ...
