Durability of Cement-Based Materials and Nano-particles: A Review
The development of modern cement and concrete industry calls for the improvement of the durability. By addition of a small amount of nano-particles nano structure of cement based materials can be modified and a higher durability can be achieved. In this paper, a review of the investigation of the effect of the frequently used nanoparticles, i.e., nano-silica, nano-clay and carbon nanotube on the durability of cement and concrete is presented. It is concluded that nanomodification of cementitious materials with nano-particle would make them durable through alteration of the physicochemical properties of the binder. Although intensive study on the usage of nano-silica has been conducted, more work is needed to get a better knowledge on the influencing mechanism. Surface-treatment of cementitous materials with nano-particles shows great potential for acquiring a durable concrete surface, and study on the selection of the treatment agent and treatment technique has been suggested. In addition, potential of using nano-clay in decreasing the transport property and the effect of carbon nanotube in optimizing the microstructure, as well as in decreasing the volume instability of cement-based materials are also discussed.
