Cementitious waste fines are a relevant alternative source for use as supplementary cementitious materials (SCMs) in clinker Portland production. Its generation surpasses slags and fly ashes, the most used ones that should become scarce in future scenarios. In literature, we do not know which is the most appropriate condition for the recycled cement/concrete fines (RCFs) as SCM. Although…
Aggregates are the most representative material of the concrete. Its characteristics affect mechanical performance of concrete. In the last decades, a reduction of the quality aggregate increasing the content of porous and weak particles is observed near metropolitan area of large cities related to regional scarcity of raw materials. This research aims: a) determining compressive strength…
Nowadays, there are only few studies aiming the improvement of the eco-efficiency of dry concretes, focusing not only on technical and economical performance, but also on the environmental aspects. Physical and mechanical properties of dry concretes depend on porosity, which is controlled by porosity, granulometric distribution, packing density of aggregates. This research aims to compar…
The circular economy is based on increasing the reuse and recyclability of materials. Currently, at the end of its life cycle, concrete cannot be fully recovered in cement and natural aggregates, even after recycling. After crushing, recycled concrete aggregates contain cement paste adhered to natural aggregates. This material does not have the same performance when used again in concrete…
Cementitious matrix's heterogeneity is the determinant factor of flaws' distributions, representing a pivotal influence on those materials' mechanical properties. The objective is to determine the variability of mechanical properties of the hardened cement pastes using different water/cement ratios and the experimental mechanical method to test particles (by Point Load test and elastic He…
Hydrated cement pastes are porous solid materials whose mechanical properties are strongly influenced by its porous structure. During the preparation of cement pastes, flaws (such as small pores and cracks) may be introduced, causing a drastic reduction in the mechanical strength. Therefore, the mechanical performance of these materials depends on the probability of these flaws to occur, …
Among the characteristics of the aggregates, its roughness can influence the performance of the concrete in both the fresh and hardened state. Aggregates with high roughness provide concrete with better strengths, as they improve the properties in the paste-aggregate interface. On the other hand, there is a reduction in the viscosity of the paste, due to the increased friction between the…

1.5 billion of tons of cementitious waste fines worldwide can be recycled as an alternative cement by thermal treatment at 500oC, without decarbonation, and somehow integrated to a CO2 capture strategy. It corresponds a half of cement production globally. Circularity and low carbon emissions for the own waste of the cement industry is still necessary and a research challenge. There is no…
The concrete recycling methods produce recycled concrete aggregate (RCA) composed of an adhered cement paste, which elevates the aggregate's porosity and harms its use in new concretes. One strategy to increase RCA quality, or the complete recover (circularity) of cement and aggregates, is the adoption of limestone filler addition in cement matrix and test different comminution methodolog…
Aggregates are the most representative material (in mass or volume) of the concrete and its characteristics affects mechanical performance of concrete, especially structural and high strength concretes. When concrete performance fails, the tendency is to increase the consumption of cement, resulting in higher CO2 footprint of concrete. In the last decades, a reduction of the quality aggre…
