“…There are several methods for estimating the abrasivity of rocks and soils. In general, three categories can be distinguished [2]: 1) Indirect methods -assessment of abrasivity by a combination of different geomechanical properties such as hardness, uniaxial compressive strength, tensile strength and other fundamental properties. [3][4][5][6][7][8][9][10][11][12][13][14][15][16]).…”

In geotechnology and mining, tools and equipment interact with aggressive geological material, causing the wear of these components. For this reason, it is important to determine the rate of abrasivity of individual geological materials, depending on the type of interaction with the tool. Various abrasivity tests have been developed in laboratories. Some of them are general, while others are special. What they all have in common is that they attempt to determine the abrasivity of rocks or soils in relation to the wear of the test specimens. This article gives an overview of the laboratory test methods for assessing the abrasivity of geological materials, which are useful in the field of geotechnology and mining engineering. General and special abrasivity tests are presented in detail. The aim of the article is to present existing laboratory tests to assess the abrasivity of rocks and soils, based on which further investigations of wear can be considered as part of a comprehensive approach to this tribological problem. Understanding of the wear mechanisms is the basis for the development of wear-resistant tools and models for predicting the tool life.

“…The direct methods for assessing abrasivity use the standard conditions to determine the abrasivity for a specific type of wear, either low or high stress or impact abrasion. The tests investigate the effects of relative movements between the geological sample and a wear tool in contact [2].…”

“…Marini et al (2011) definen la abrasión de las rocas como «el desgaste causado por la acción de elementos que, al entrar en contacto con la superficie, retiran una pequeña o gran cantidad de material de la superficie» y afirman que es un factor importante de envejecimiento de la piedra natural, incrementándose su acción con el tiempo. Golovanevskiy y Bearman (2008) explican que la abrasividad es una propiedad que refleja el efecto abrasivo de las rocas y minerales al contacto con otros materiales y, por lo tanto, de gran importancia en la vida útil de los materiales y eficiencia en el procesado de minerales y equipos de trabajo.…”

Resumen: La abrasividad de las rocas tiene gran influencia en algunas de sus aplicaciones, como en los sectores de la piedra natural y en el de ingeniería y obra civil. Para su cuantificación existen más de 15 métodos de ensayo. En este trabajo se hace una revisión de estos métodos clasificándolos en dos grandes grupos: en el caso de la piedra natural se considera el desgaste de los materiales rocosos en contacto con un útil de desgaste, mientras que, en obra civil, por el contrario, se presta atención al desgaste que la roca provoca en los útiles de corte o perforación. Por otra parte, se consideran también aquellos métodos en los que la abrasividad de las rocas se define en función de la variación del valor de alguna de sus propiedades.Palabras clave: Abrasividad, metodos de ensayo, rocas, propiedades fisicas, petrografia.Abstract: The abrasiveness of the rocks has a great influence in some of their applications, such as in the natural stone and in the civil engineering sectors. There are more than 15 test methods for its quantification. This work summarizes these methods and their classification into two large groups: in the case of natural stones the wear of the rock materials when in contact with a wear tool is taken into account; on the other hand, in civil engineering attention is paid to the wear that the rock causes in the cutting or drilling tools. In addition, those methods, in which the abrasiveness of rocks is defined according to the variation of the value of some of its properties, are also considered.Keywords: Abrasivity, testing methods, rocks, physical properties, petrography.

“…Ela não pode ser muito alta ou muito baixa, pois isto poderia levar a um insuficiente ou excessivo desgaste da ferramenta. Nesse contexto, o nível de dureza Rockwell de 40/42 HRC foi selecionado como o adequado para testar uma série de rochas, cobrindo uma boa faixa de abrasividade (Golovanevskiy;Bearman, 2008).…”

ResumoEsse trabalho emprega o método para avaliar a abrasividade proposto por Golovanevskiy e Bearman (2008). Esse método, ensaio de abrasão por impacto deslizante (Gouging Abrasion Test), é realizado em condições de alta tensão/alto impacto de desgaste. O método consiste de uma ponteira cilíndrica com uma ponta cônica de 90º, que, em trajetória pendular, atinge uma amostra de rocha com energia de impacto de 300 J e velocidade da ordem de 5,2 m/s. O Gouging Abrasion Index (Gi) é calculado como sendo a média do diâmetro da ponta cônica, após desgaste, em milímetros e o resultado é multiplicado por 10. Esse trabalho verificou a adequabilidade do Gouging Abrasion Test, para um pequeno número de amostras de rocha, que representam, qualitativamente, os principais tipos de rocha encontrados em trabalhos de corte, perfuração e britagem no Brasil, e a sua correlação com outros ensaios consagrados como a resistência à compressão, o desgaste Amsler e a dureza Knoop. Essa análise mostrou alta correlação entre Gi e a dureza Knoop (R² = 0,94), baixa correlação com o desgaste Amsler (R² = 0,41) e nenhuma correlação com resistência à compressão uniaxial. Palavras-chave: Mecânica de rochas, abrasão, esclerometria pendular. Abstract This paper employs the method for evaluating abrasion proposed by Golovanevskiy e Bearman (2008). This method, Gouging Abrasion
