Silica fume (SF) and Metakaolin are cementitious materials used as admixtures to produce high strength concrete and to reduce the permeability. Also, Silica fume is used to make durable concrete structures in combination with ordinary Portland cement. In places where insufficient or poor curing concrete structures like sea shores, underground structures which undergo severe loss of compressive ...

To improve the blast resistance of a wall system, it is necessary to enhance its energy absorption capabilities and/or increase its mass. Much research has been performed on improving the ductility, and thus the resistance, of a wall system using elastic materials externally attached to the tension side of a wall. This project investigated the static resistance of wall systems with elastic mate...

Concrete structures are increasingly affected by fatigue damage, while new slender building with greater mechanical requirements make it necessary to deepen knowledge of their behaviour under loading. In this research, high-strength plain concrete was studied two different frequencies cyclic compressive stress. Wöhler curves were obtained in ways, on the one hand, applying a uniform frequency 1...
