Investigation Of Scientific And Technical Factors Of Dehbid Marble

In the following tables, which have been presented in specialized laboratories of the University of Tehran at the request of weight stone for technical and scientific study of the structure of Dehbid marble (known as Crema Marfil Marble), you can see all the technical and structural factors of Dehbid Shayan marble.
This research has been done at the request of one of the customers to advance the principles and the correct choice of materials.

Among the items studied in the following tables, including physical characteristics, elements in the rock, tensile-abrasion, and flexural strength at different temperatures, water absorption, porosity, and density have been studied.
