Concrete Structure - an overview ScienceDirect Topics

Concrete structures, especially reinforced concrete structures are one of most common type of structures used around world. The coupling between steel and concrete allows engineers to design composite structures considering complex architectural geometries with fair costs. When these structures are located in nonaggressive environments, they respect, in general, the structural life

Concrete Structure - an overview ScienceDirect Topics

Concrete structures are relatively good at resisting the effects of damage caused by fire. Concrete is a poor conductor of heat and thermal conductivity is reduced as the temperature increases. However, if concrete is exposed to a rise in temperature, the water contained in its pores and capillaries is first driven off. Should the temperature increase to above 100 °C, some of the water ...

Reinforced Concrete Structure - ScienceDirect

Lars-Olof Nilsson, in Developments in the Formulation and Reinforcement of Concrete (Second Edition), 2019. 5.3.1 Conclusion. Reinforced concrete structures are vulnerable to two types of corrosion—corrosion initiated by carbonation and corrosion initiated by chlorides. A concrete material with w/c ratio below 0.4 will be so resistant to the ingress of the carbon dioxide that would cause ...

Hybrid concrete (HC) structures are being promoted in China, as well as in other countries. The construction process of HC structures differs from that of traditional cast-in-situ (CiS) structures in two aspects: 1) the construction unit for HC structures is no longer a floor or a construction zone, but a single component, 2) both PC components and CiS components exist in HC structures, and ...

27/05/2018  For instance, for a 100-year service life and a reliability index of β = 1.28, the required cover depth for the sound concrete condition is 35 mm for precast concrete and 40 mm for cast-in-place concrete. This shows that the required cover depth for the design service life of an RC structure may depend on the concrete casting method, even if the structures are placed in the same carbonation ...
