Analysis of Gandomak marble
The minimum porosity for building stone is 0.00 and the maximum is 2.5, and the porosity of Gandmak Shiraz marble is 0.74 and it is seen without porosity in appearance, so the porosity of this stone is at the optimal level
The minimum specific weight for this category of building stone is 2.5 and the maximum is 2.8, and the porosity of Gandamak Shiraz marble is 2.65, so the specific weight of this stone is optimal.
The minimum abrasion resistance of construction stone is 2.5 and the maximum is 6, the abrasion resistance of Gandamak Shiraz marble is 2.8, as a result, the abrasion resistance of this stone is appropriate as in many national and international projects such as Iranmal. It has been used a lot.
The minimum compressive strength for this category of building stone is 500 and the maximum is 1500. The compressive strength of Gandamak Shiraz marble is 621. As a result, the compressive strength of this stone is optimal.The minimum amount of water absorption for this category of building stone is 0.3 and the maximum is 1.5, the amount of water absorption of Gandamak Shiraz marble is 1, as a result, the amount of water absorption of this stone is optimal, as an example in all ponds and And the old baths of Shiraz were in direct contact with the water, the marble of Gandmak Shiraz was used.
General conclusion from the analysis of Gandamak Shiraz marble:
The best evidence is that the cultural heritage organization uses Gandamak marble for its building marble in the form of: raw Gandamak marble, axed Gandamak marble, and polished Gandamak marble and in modern projects in the Azim library of the University of Science and Technology. Iran has used sandblast sandblast sandblast sandblast sandblast sandblast stone, Bushhammer sandblast stone.Despite its long-standing use and the mentioned evidences and certificates, Gandamak marble can be recommended for use in the exterior and interior of the building
