Análise sistemática de parâmetros que influenciam nas propriedades endurecidas de concretos permeáveis.

Abstract

Increasing urbanization, such as building construction and paved roads, leads to a progressive increase in soil waterproofing. Because of this reason, flooding problems have occurred more frequently, as the process hinders the natural drainage of water and, as a consequence, greater problems occur, such as environmental pollution, basic sanitation problems and floods, increased noise levels, among others. In view of this problem, there are several researches looking for solutions that are capable of reducing soil impermeability. Among them, permeable concrete, a material with high porosity that has a high permeability value compared to conventional concrete has proved to be an excellent alternative to minimize these problems. Although there are several studies on this type of concrete, it is not popularly known. Therefore, in view of this context, the present study aimed to analyze studies on the characteristics and possibilities of using permeable concrete. For this, a systematic review of the literature was carried out, gathering analyzes and comparisons between studies that addressed this theme. According to the works reviewed here, it was possible to verify that one of the greatest difficulties in making this concrete is to try to achieve an increase in mechanical strength and maintain efficient permeability. In general, this work showed that the use of permeable concrete brings direct advantages to the population and to nature by allowing a greater flow of water through the concrete, making the water reach the soil. However, the disadvantages of using this concrete were also analyzed, such as the need for periodic maintenance to mitigate pore clogging.
