A systematic review is carried out to determine the influence of recycled aggregate on the properties of concrete designed for pedestrian pavers, selecting highly relevant investigations, filtering them by years, focus and results. Which contribute to make a comparison of results in the properties of resistance to compression and percentage of absorption of pavers subjected to different percentages of replacement of recycled aggregate in its structure, in order to determine the influence, they have on said properties. Through the analysis and synthesis of results, the influence of the recycled aggregate is validated, affecting the decrease in its resistance to compression and the increase in the percentage of absorption. However, taking into account the information presented and based on the statistics, it is valid to conclude that by replacing up to 25% of the coarse aggregate with recycled aggregate, an adequate mixture can be achieved, complying with the parameters estimated by NTP. 399,611 according to their properties. Likewise, it is valid to mention that, at a higher percentage of replacement, the properties vary unfavorably

“…In the environmental aspect, the rapid increase in the amount of industrial waste is one of the main reasons that has led countries to adopt stricter environmental and sustainable policies (Sangi-Gonçalves et al, 2022). However, it is necessary to estimate the effect of the use of bricks as concrete aggregate to implement it as a component of concrete (Moreno et al, 2019). Thus, the total or partial substitution of this component is a key challenge to address the negative environmental effects and costs associated with the aggregate extraction process, without significantly affecting the properties of concrete and mortar manufactured with them (Feijoo et al, 2021).…”

Refractory brick waste, added to the fires originated in structures, makes it possible to bring together two problems to contribute to sustainable construction and introduce new aggregate alternatives in concrete. The objective of the study was to produce concrete with less fine aggregate and to evaluate a more sustainable concrete, using refractory brick residues (RBR) to replace fine aggregate in five percentages 10 %, 20 %, 30 %, 40 % and 50 % to be exposed to direct fire. The design was based on a water-cement w/c ratio of 0.71 and the production of 144 RBR-based concrete specimens. The fresh samples were subjected to slump and fresh unit weight tests, the cylindrical specimens prepared after 28 days of curing were subjected to compressive strength at room temperature and various temperatures (200 to 1 000 °C) for different times of 15, 30 and 60 minutes. In addition, a Three Factor statistical analysis of variance was performed with respect to the compressive strength at 28 days. The results showed that the RBR influences the concrete mix are less workable and reduce the fresh unit weight at higher substitution percentages. On the other hand, the ideal dosage was with the percentage of 40RBR as opposed to the other dosages subjected to heat, being insignificant at 15-minute exposure, but relevant at 30 and 60 minutes. It is concluded that RBR significantly influences the improvement of its mechanical properties under high heat and the amount of residues is limited to a specific dosage, providing a sustainable constructive approach to direct controlled fire exposures.

“…Respecto al concreto, puede considerarse que éste es un material compuesto por dos partes: la primera que es un producto pastoso y moldeable, que tiene la propiedad de endurecer en un determinado tiempo [13], y la segunda es que son trozos pétreos que quedan englobados en esa pasta. Al mismo tiempo, la pasta está compuesta por agua y un producto conglomerante o aglomerante, el cual es el cemento.…”

The objective of this research is to evaluate the compressive strength of concrete f'c=175 kg/cm² with the improvement of Whole Coffee Husks (CCE) and Ground Coffee Husks (CCM) in percentages 0.5%, 1.5% and 2.5% with respect to the weight of the fine aggregate in the concrete mix. The investigation is of the experimental type with a quantitative approach, where a total of 63 units of standardized cylindrical concrete specimens are sampled. The instruments used for data collection were based on the ASTM regulations for carrying out laboratory tests for aggregates, preparation of test tubes and breaking them, for data analysis Excel spreadsheets were used.In the results it was obtained that the optimal improvement is 0.5% in the case of the CCE and 1.5% in the case of the CCM, since they improve the compressive strength of the concrete at 28 by 8.69% and 3.68% respectively. days of curing On the other hand, the additions of 1.5% and 2.5% of CCE and 0.5% and 2.5% of CCM, generated a decrease in resistance of 12.45%, 23.42%, 13.98% and 29.59% respectively.
