Abstract
There is an international concern for reducing energy consumption and protecting environment by application of circular economy principles in the construction industry. The thermal resistance of concrete plays a significant role in the energy efficiency of a building, and this can be improved by using concrete products with high thermal resistance. This study analyzes the influence of perlite, as an addition, on the physico-mechanical properties of concrete, with the aim of identifying perlite concrete products that will respond to the improvement of the heat transfer resistance of the building envelope. The study examines the effect of replacing different amounts of concrete aggregates with perlite in percentages of 10%, 20%, 30% and 100%. The results show that the replacement of sand with perlite improves the thermal performance of concrete, but its mechanical properties are negatively affected. The research carried out highlighted that perlite can be successfully introduced in the production of concrete blocks used for external non-bearing walls pannels, the outstanding feature being the reduction of energy consumption in buildings. Overall, the paper identifies an efficient and environmentally friendly way of using perlite in the construction industry, improving the energy performance of buildings, and reducing the environmental impact of construction wastes.
