Compressive Strength Of Marble

Both granite and marble are natural stone.
Compressive strength of marble. The obtained results confirm the suitability of studied samples as a decorative stones for building ornamentation and garden tiles. Properties of marble marble is a highly durable stone and is used for countertops flooring stairs. This abstract is a brief summary of the referenced standard. Depending on the limestone and the mineral combination within the marble most marble rates from three to five on the mohs hardness scale.
Scientists have tested and documented the full range of granite and all its capabilities. Marble is limestone that has been compacted and heated over millions of years. So compressive strength is the highest load per unit area borne by the stone without giving in. There are 17 material properties with values for both materials.
The physical property requirements to which marble stones shall adhere to are absorption by weight density compressive strength modulus of rupture abrasion resistance and flexural strength. Compressive strength is the stress in pounds per square inch psi that will rupture a stone sample. The radiation emission of marble is very low compared to other marbles which is 15 times less than the tolerance of. As a result marble is less porous and slightly stronger than limestone but still less durable than granite.
A dry density result of granite is 2 69 and marble dry density is 2 62. For the dry condition the stone specimens are dried in an oven at 60 c 2 c 140 f 2 f for at least 48 hours or. These values determines it s strength which measures its ability to resist stresses. Very rarely is the compressive strength of a stone much of a factor in stone selection.
The hardness of marble is 3 4 whereas its compressive strength is 115 00 n mm 2. A stone floor has to withstand loads of people and heavy objects. Properties with values for just one material 1 in this case are not shown. This test is vital for evaluating the stone s resistance to crushing loads.
A wall stone has to bear the compressive load of the stone s weight. Luster of marble is the interaction of light with the surface of marble. The altai marble is eco friendly product with low health impact to environment. A column of stone with a density of 160 lbs cf that is 100 feet tall exerts a compressive stress of only 110 pounds per square inch.
Streak is the color of rock when it is crushed or powdered. The streak of marble is white whereas its fracture is not available. Below is the property range of values for granite. The compressive strength test of granite is ranging from 1050 to 1358 kg cm 2 for marble the results ranging from 827 to 1020 kg cm 2.
Since the strength may vary when the stone is wet the strength tests i e. Compressive strength flexural strength modulus of rupture are sometimes performed using wet stone specimens.
