Proteção superficial de baixo custo com materiais artificiais para controle de erosão em taludes

Abstract

Slopes are defined as steep inclines and declivities on a terrain or surface, representing geological contexts highly susceptible to erosive processes. The study of erosive processes is grounded in the need to ensure safety in high-risk areas and environmental preservation. The high cost associated with measures to combat these processes underscores the importance of studies aimed at investigating low-cost possibilities, especially in the context of combating water erosion. Based on this, the present study aims to investigate low-cost surface protections for application on slopes located in high-risk areas. To achieve this, artificial materials were tested in terms of infiltrability and resistance to water impact, assessed through infiltration tests and surface runoff tests, respectively. The cement-water mixture yielded promising results in terms of infiltration time, as well as a good thickness and resistance of the surface protection layer after the three tests. The mixture also demonstrated strong resistance to water erosion. On the other hand, the paint-water mixture showed favorable results in terms of infiltration time, along with a greater thickness of the surface protection layer compared to the cement-water mixture, albeit at a higher cost. This mixture also exhibited strong resistance to the water erosion process. These findings contribute to an understanding of erosive processes and serve as an encouragement for future research aimed at identifying low-cost solutions to combat highly susceptible erosion scenarios.
