Abstract

Concrete bridges are very popular in Vietnam. However, under severe environments of the tropical climate, they can be lead to defects or deterioration with excessive rate. This point demands on materials performance with respect to extremes in not only stress and strain but also the properties of cementitious materials in practical design. In addition, cracking, shrinkage and creep of concrete due to the rapid ambient conditions of temperature and humidity are also a major challenge to researchers in Vietnam. Therefore, improving the sustainability of bridges by applying high performance concrete is very necessary. Recent developments in nanotechnology have given a lot of new challenges to produce the eco-friendly high performance concrete. It has been found out that use of nanotechnology through using nano-silica as a mineral admixture to modify the properties of the cementitious materials has significantly improved the performance of concrete. This paper investigates the effect of nano-silica as an addition on new concrete generation, the advancements in nanotechnology on the properties and performance of cementitious materials; and the application to concrete bridges in Vietnam in near future for sustainable development purpose.
