Abstract
The performance of large-diameter circular saws on eight carbonate rocks was recorded and indentation hardness, density and porosity tests were undertaken on the five travertines, two limestone and one dolomitic limestone samples returned to the laboratory. A strong linear correlation between indentation hardness index values and the hourly production of the circular saws was found. The slab production was slowest for the dolomitic limestone rocks with the highest indentation hardness, lowest porosity and highest density values.
Résumé
Les performances de scies circulaires de grand diamètre, pour la découpe de huit roches carbonatées représentées par cinq travertins, deux calcaires et un calcaire dolomitique ont été enregistrées. La densité, la porosité et un paramètre de résistance à l’indentation ont été mesurés au laboratoire sur les échantillons correspondants. Une forte corrélation linéaire entre l’indice de résistance à l’indentation et la production horaire des scies circulaires a été trouvée. La production de plaques était la plus faible pour les calcaires dolomitiques qui présentaient les plus fortes résistances à l’indentation, les plus faibles porosités et les plus fortes densités.
