To this end, two stations were developed using the Arduino development platform together with meteorological sensors, one designed for data collection in external environments and the other for data collection in internal environments. The calibration process lasted approximately 2 hours and was carried out inside a climate-controlled chamber through comparison with data collected from already calibrated measuring equipment. Based on this comparison, it was possible to adjust the output data provided by the proposed meteorological stations. At the end of the work, an R² coefficient very close to 1 was obtained for both stations, which indicates that the sensors used in the proposed stations are reliable. However, reading the graphs leads us to believe that to actually validate the internal station sensor, a longer measurement period would be necessary.

The sand from the processing of iron ore has been widely used in civil construction in Brazil, especially in the states of Minas Gerais, Espírito Santo and São Paulo. It is used as fine aggregate in the production of mortars, cement products and concrete. With the possibility of producing new sand in several iron ore mines in the state of Minas Gerais, the present study aimed to develop and analyze concrete dosages with various ore sands and sands present in the industrial market in the Belo Horizonte region. The replacement of natural river sand with mining sand in concrete dosages was evaluated and the Abrams curves were analyzed for the various dosages developed. It was possible to observe a performance gain in the dosages carried out with ore sands, with a reduction of up to 7% in cement consumption in the mixes. Thus, it can be concluded that the use of mining sand in the production of concrete is efficient, with technical and productive gains, promoting sustainable construction, reducing CO2 and promoting the circular economy in the construction chain.

Published: August 2024

The high demand for concrete production raises concerns about regional shortages of aggregates such as sand. The strength characteristics of sand depend directly on its origin. This article evaluates the influence of using natural sand (compared to standardized Brazilian sand) on the properties of fresh and hardened state of cementitious composites employing two types of Portland cement, CP-V and CPIII. The results show that the consistency index is lower for mortars with natural sand and CP-V. Although statistically equivalent, the absolute values of compressive strength at 28 days for mortars with natural sand appear to be similar or slightly higher than those measured for mortars with Brazilian standardized sand. This may be related to the higher presence of fine particles, both in natural sand and in CP-V cement. Therefore, the importance of proper understanding of each material in the workability and mechanical performance of concrete is emphasized.

Application of the ecosystem approach in Life Cycle Assessment
Authors: da Rocha Marina Silva Seabra , de Assis Eleonora Sad
Published: August 2024

There has been a search for standardized and coherent methods for evaluating environmental performance in the construction sector. Despite its limitations, LCA has been the most used method to perform this task. Given its potential, this study aims to propose an improvement of the methodological and conceptual framework of the LCA model, focused on assessing the environmental performance of construction materials. The aim is to incorporate the precepts of ecosystem theory to mitigate its flaws. Analyzing the LCA normative and making a conceptual comparison with the ecosystem foundations, it was possible to embody the cascade framework and the impact categories of the ecosystem’s approach in the LCA model. The result was the expansion of the system boundaries and the consolidation of a new characterization model.
