Due to the different applications of natural marble, its industrial technical requirements have different focuses.
Natural marblemarble blocks
The main requirements of the building materials industry standard (JC202-92) for natural marblemarble blocks are as follows:
Marble blocks must have the shape of a right-angled parallelepiped.
The size of marble blocks requires a length greater than or equal to 100cm, a width greater than or equal to 50cm, and a height greater than or equal to 70cm.
The appearance quality of marble requires that the hue patterns of the same batch of marble blocks should be basically the same; the appearance quality grades such as missing corners, missing edges, and cracks of marble blocks should meet the requirements of Table 4.25.6.
The physical performance requirements of marble (JCT202-2001): bulk density is not less than 2.6g/cm3; water absorption is not more than 0.5%; dry compressive strength is not less than 50MPa; bending strength is not less than 7.0MPa.
