How to identify high-quality marble slabs?

To identify high-quality marble slabs, you first need to pay attention to their physical properties and surface quality. We can evaluate from the following aspects:

Physical properties: including compressive strength, flexural strength, water absorption bulk density, etc. These indicators are important technical performance indicators for judging the quality of natural stone materials.

Surface quality: including three-dimensional detection and evaluation of surface pattern tone, surface microtopography, and stone image preprocessing through image processing technology. This involves the application of the glossiness calculation model of the stone surface, and the detection of surface quality through the focused synthesis three-dimensional reconstruction principle and the surface glossiness calculation model.

Inspection methods and means: Detailed introduction based on national standards (GB), European standards (EN), and American standards (ASTM), and analysis and discussion of the main technical changes between the old and new versions of national standards. At the same time, considering the rich variety and variety of stone products, it is necessary to have reasonable inspection methods and means to inspect according to inspection standards and inspection rules.

Environmental adaptability: Considering that in recent years, with the development of the domestic construction and decoration industry and the continuous improvement of people's awareness of low-carbon environmental protection, natural stone has been increasingly widely used in the construction and decoration industry. Therefore, choose products that produce a return-to-nature effect and are not replaced by any artificial materials.

When identifying high-quality marble slabs, comprehensive consideration should be given to their physical properties, surface quality, and compliance with relevant national standards and environmental protection requirements.
