| Portland cement is the major chemical product processed in the world, more than 3.6 Bton at 2011, causing important environmental impacts. Several nano-particles have been tested in cement based materials in order to improve their performance and durability leading to an eco-efficiency use for this binder. Published researches for nano-particles in cement based materials have been demonstrated optimum volumes contend considering the relative strength gain, directly related with packing and nucleation effect observed for nano-particles, and a pozzolanic reaction is observed for nano-SiO2. |
