Compressive Strength Of Marble

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.

Compressive strength of marble.

There are 17 material properties with values for both materials. Compressive strength is the stress in pounds per square inch psi that will rupture a stone sample. 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.

In addition international laboratory tests has confirmed that marble has compressive resistance strength of 44 3mpa after freezing. Properties with values for just one material 1 in this case are not shown. 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 flexural strength modulus of rupture are sometimes performed using wet stone specimens.

This abstract is a brief summary of the referenced standard. As a result marble is less porous and slightly stronger than limestone but still less durable than granite. 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.

This test is vital for evaluating the stone s resistance to crushing loads. The hardness of marble is 3 4 whereas its compressive strength is 115 00 n mm 2. Very rarely is the compressive strength of a stone much of a factor in stone selection. Luster of marble is the interaction of light with the surface of marble.

Since the strength may vary when the stone is wet the strength tests i e. Scientists have tested and documented the full range of granite and all its capabilities. A wall stone has to bear the compressive load of the stone s weight. A stone floor has to withstand loads of people and heavy objects.

The obtained results confirm the suitability of studied samples as a decorative stones for building ornamentation and garden tiles. A dry density result of granite is 2 69 and marble dry density is 2 62. Depending on the limestone and the mineral combination within the marble most marble rates from three to five on the mohs hardness scale. Both granite and marble are natural stone.

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. Luster of marble is dull to pearly to subvitreous. 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. For each property being compared the top bar is granite and the bottom bar is marble.
