Classification of Parameters Affecting Impact Resistance of Natural Stones

Abstract

This study used various test methods to analyze the impact resistance of marble, limestone, and travertine to determine their breaking potential when they are used for interior and exterior floor covering. A total of 17 kinds of natural rocks (7 marbles, 5 travertines, and 5 limestones) were categorized according to their commonly used geological formations and were subjected to various characterization tests (mineralogical and petrographic characteristics, chemical properties, as well as physical and mechanical properties). The rupture energy caused by an impact on natural rocks was determined according to the BS EN 14158 standard, whereas restitution coefficients were determined according to the BS EN ISO 10545-5 standard. The impact resistance, rupture energy, and restitution coefficient of polished natural stone plates that were used in the tests were statistically analyzed. The parameters that affected these variables of natural rocks were plate thickness, mineralogical and petrographic characteristics, and physical and mechanical properties. Finally, the potential fractures of the specimens were classified based on impact resistance, rupture energy, and restitution coefficient.

“…The ball was raised in 5 cm increments until it broke the test specimen. The impact resistance (L) was calculated using the following equation 15,33 : $$$$\begin{equation}L = \frac{{m \times g \times h\;}}{t} \times 10\end{equation}$$$$where L is the impact resistance (J/cm), m is the mass of the ball (kg), g is the gravitational acceleration (9.086 m/s 2 ), h is the height at which the ball was dropped (m), and t is the sample thickness (mm).…”

Petrological and Geochemical Properties of Greek Carbonate Stones, Associated with Their Physico-Mechanical and Aesthetic Characteristics

“…Simplified table including average CaO/MgO ratios, mineralogical, geochemical and physico-mechanical properties for every type of rock along with their standard deviation (from Tables S1 and S2) of the 73 selected Greek carbonate ornamental stone samples. The majority of the samples tested display rupture energy values that range between four (4) and six (6), suggesting that they possess an extremely low breaking potential [48,51]. It should be noted that most of these rocks have been affected by metamorphic and recrystallization processes, displaying almost exclusively white and grey colours.…”

“…Based upon the petrographic observations, these samples are characterized by their rather small-sized calcite and dolomite grains, as well as by their low porosity. Both of these factors seem to be closely associated with high levels of frost resistance and flexural strength [47][48][49][50].…”

“…Birçok araştırmacının yaptıkları çalışmalarda, doğal taş örneklerinin kopma enerjisi, çarpma dayanımı ve farklı bir cihaz ile de sıçrama katsayısı değerlerinin belirlemesi için bir deney yöntemi geliştirmeye çalışılmıştır [14][15][16][17][18]. Bu çalışmada, zemin döşeme malzemelerinin kopma enerjisi ve çarpma dayanımı verilerinden yararlanılarak, kırılma gerilmesi belirlenmiştir.…”
