Physicomechanical characteristics and durability of the cement pastes containing fly ash (FA) and iron-oxide nanoparticles (NI) showed that workability was reduced with the FA addition, although it was counterbalanced when ...

The durability of concrete is influenced by its porous network. The use of fly ash in concrete mixtures produces additional hydration products, changing its micro-structure. As a concrete admixture, fly ash not only improves ...

Portland cement is the worldwide most commonly used material in construction. However, it is known that the Portland cement industries have a significant negative impact in the environment. For this reason, there is a study ...

This study encompasses the analysis of mechanical properties, durability and cost-effectiveness of concrete mixtures with nanosilica particles, silica fume and fly ash utilized as admixtures. The cost of materials for the ...
