En raison des diff\u00e9rentes applications du marbre naturel, ses exigences techniques industrielles sont diff\u00e9rentes.<\/p>\n
Marbre naturelblocs de marbre<\/p>\n
Les principales exigences de la norme de l'industrie des mat\u00e9riaux de construction (JC202-92) pour les blocs de marbre naturel sont les suivantes :<\/p>\n
Les blocs de marbre doivent avoir la forme d'un parall\u00e9l\u00e9pip\u00e8de rectangle.<\/p>\n
La taille des blocs de marbre n\u00e9cessite une longueur sup\u00e9rieure ou \u00e9gale \u00e0 100 cm, une largeur sup\u00e9rieure ou \u00e9gale \u00e0 50 cm et une hauteur sup\u00e9rieure ou \u00e9gale \u00e0 70 cm.<\/p>\n
La qualit\u00e9 d'aspect du marbre exige que les teintes d'un m\u00eame lot de blocs de marbre soient fondamentalement les m\u00eames ; les degr\u00e9s de qualit\u00e9 d'aspect tels que les coins manquants, les ar\u00eates manquantes et les fissures des blocs de marbre doivent satisfaire aux exigences du tableau 4.25.6.<\/p>\n
Les exigences de performance physique du marbre (JCT202-2001) : la densit\u00e9 apparente n'est pas inf\u00e9rieure \u00e0 2,6g\/cm3 ; l'absorption d'eau n'est pas sup\u00e9rieure \u00e0 0,5% ; la r\u00e9sistance \u00e0 la compression \u00e0 sec n'est pas inf\u00e9rieure \u00e0 50MPa ; la r\u00e9sistance \u00e0 la flexion n'est pas inf\u00e9rieure \u00e0 7,0MPa.<\/p>\n
