Abstract(s)
Nowadays, the use of nanomaterials (NM) to improve the performance of cement and concrete matrixes constitutes a potential alternative to the exclusive use of Portland cement (PC). Similarly, there is currently no doubt in the construction industry (CI) about the pressing need to reduce the consumption of PC. The CI represents the world's third-largest industrial energy consumer, and the component related to the production of PC alone represents 7% of the carbon dioxide (CO2) emissions globally (OECD, 2018). PC is undoubtedly the most used material in construction in terms of its relative volume. Raw materials for PC production are generally plentiful and they are also available throughout the world. It is possible to state that, , at this moment, there is no other material with the same availability as the PC, which might be able to fulfil the construction’s technical requirements as the concrete’s main component. In this sense, it is imperative that the cement industry obtains viable technical solutions that allow the reduction of PC consumption. That reduction can be achieved either by its direct replacement with another material (e.g. using fly ash), or by improving the cement and concrete matrix performance with the addition of new materials, such as NM. This second option is quite interesting, since it allows u s to maintain the cement and concrete matrix properties/characteristics, reducing PC consumption by adding a tiny amount of a NM.
