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 ...

In order to evaluate the tensile strength of concrete made with a shrinkage-reducing admixture (SRA) along with fly ash, nine mix designs were prepared and tested at ages of 3, 5, 7, 14, 28, and 56 days under different ...

This thesis presents results from a comprehensive laboratory study carried out to investigate the feasibility of using Circulating Fluidized Bed Combustion fly ash for improvement of engineering properties, particularly ...

Coal has been a major energy source since the Industrial Revolution. Despite its environmental problems, coal consumption is still growing because of the lack of alternatives such as natural gas and petroleum resources. ...

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 ...
