Compressive Strength Of Marble

The altai marble is eco friendly product with low health impact to environment.

Compressive strength of marble.

For each property being compared the top bar is granite and the bottom bar is marble. Luster of marble is the interaction of light with the surface of marble. Marble is limestone that has been compacted and heated over millions of years. Properties with values for just one material 1 in this case are not shown.

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. A dry density result of granite is 2 69 and marble dry density is 2 62. In addition international laboratory tests has confirmed that marble has compressive resistance strength of 44 3mpa after freezing. 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.

As a result marble is less porous and slightly stronger than limestone but still less durable than granite. Properties of marble marble is a highly durable stone and is used for countertops flooring stairs. Luster of marble is dull to pearly to subvitreous. This test is vital for evaluating the stone s resistance to crushing loads.

So compressive strength is the highest load per unit area borne by the stone without giving in. Compressive strength flexural strength modulus of rupture are sometimes performed using wet stone specimens. Compressive strength is the stress in pounds per square inch psi that will rupture a stone sample. A stone floor has to withstand loads of people and heavy objects.

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. The hardness of marble is 3 4 whereas its compressive strength is 115 00 n mm 2. Both granite and marble are natural stone. Very rarely is the compressive strength of a stone much of a factor in stone selection.

This abstract is a brief summary of the referenced standard. 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. 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. There are 17 material properties with values for both materials. Below is the property range of values for granite.

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. The radiation emission of marble is very low compared to other marbles which is 15 times less than the tolerance of.
