Compressive Strength Of Marble

Luster of marble is the interaction of light with the surface of marble.

Compressive strength of marble.

So compressive strength is the highest load per unit area borne by the stone without giving in. The streak of marble is white whereas its fracture is not available. 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. Both granite and marble are natural stone.

Marble is limestone that has been compacted and heated over millions of years. Streak is the color of rock when it is crushed or powdered. Depending on the limestone and the mineral combination within the marble most marble rates from three to five on the mohs hardness scale. The hardness of marble is 3 4 whereas its compressive strength is 115 00 n mm 2.

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. These values determines it s strength which measures its ability to resist stresses. A wall stone has to bear the compressive load of the stone s weight. Scientists have tested and documented the full range of granite and all its capabilities.

The obtained results confirm the suitability of studied samples as a decorative stones for building ornamentation and garden tiles. This abstract is a brief summary of the referenced standard. Compressive strength flexural strength modulus of rupture are sometimes performed using wet stone specimens. 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.

Below is the property range of values for granite. Properties with values for just one material 1 in this case are not shown. The radiation emission of marble is very low compared to other marbles which is 15 times less than the tolerance of. Very rarely is the compressive strength of a stone much of a factor in stone selection.

Properties of marble marble is a highly durable stone and is used for countertops flooring stairs. In addition international laboratory tests has confirmed that marble has compressive resistance strength of 44 3mpa after freezing. A stone floor has to withstand loads of people and heavy objects. 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.

This test is vital for evaluating the stone s resistance to crushing loads. A dry density result of granite is 2 69 and marble dry density is 2 62. For each property being compared the top bar is granite and the bottom bar is marble. Since the strength may vary when the stone is wet the strength tests i e.

As a result marble is less porous and slightly stronger than limestone but still less durable than granite. Compressive strength is the stress in pounds per square inch psi that will rupture a stone sample.
