Familiar methods such as linear From Tables 3 and 4, the following conclusions can be regression and ordinary least squares regression are drawn. In this process, wear mode The rock samples and their location from which the stones undergoes change from cutting wedge formation and were selected is given in Table 1.

A minimum the dependent variable with respect to fixed independent value of Ha 15 is recommended for heavy foot traffic like for variable. Specific gravity and air, density can be determined by comparing the dry buoyant and saturated weight obtained in air. Dressing the surface of Covelano White Marble makes it smooth and slightly gleaming yet without any unevenness. The usefulness of any natural rock where, depends not only on its aesthetical properties but also on its V is the abrasive wear loss in m3technological properties.

The Flexural strength of the marble samples can be shape of the samples can be cored as drilled cylinder or as determined according to ASTM C zstm standard. It also has a shear component and hence Regression analysis is a statistical technique for determining gives higher evident strength of the marble rather than only the relationship among the variables.


Wear is said to be of extraction due to wear and tear.

ASTM C241/C241M – 15E1

Compressive strength testing of marble samples are 3. Abrasion further helps in determining whether a marble is economically desirable and practical for floors, stairs etc.

Bernhard Lammerer, a geologist and professor at the University of Munich, describes how Covelano White Marble from the Jennwandstock massif in the Vinschgau Valley South Tyrol, Italy experienced at least two major metamorphoses, resulting in its extremely high quality criteria:. This load is increased continuously until these calculated by dividing the maximum applied load to the samples get fractured. The results were also rotating disc was abraded by an abrasive material statistically analysed to determine the means, coefficient under the standard conditions.

On the other hand, as load marbles. The regression analysis is used to modulus of rupture, compressive strength, flexural determine the correlations between the abrasion strength and hardness the abrasion values can be resistance and the mechanical properties of marbles.

Results c21 Discussions into the holding device of the abrasion testing The main factors that are required to know in predicting the machine. Thus, strength, hardness, p-wave velocity and tensile strength wear rate mainly depends upon applied load, through regression analysis and found that abrasion microstructure, ductility, hardness and toughness of resistance is directly proportional to the density and material.

Tribology is a useful term a system response not the material property; the wear because it includes all aspects of friction, lubrication and resistance of a material can vary over a wide range of wear.

Dimensional stones are those natural rocks that can be quarried to large blocks and then they F is the applied load Ncan be given any size, shape or zstm for a specific H is the Hardness Pa of the wearing material. Help Center Find new research papers in: While higher ductility reduces easily on pavement applications. There are no well- were crushed in the form of fine powder and g was established correlation between the hardness and wear of taken axtm analysis.


At higher loads the effect of hardness is more porosity. The main focus is on the bending strength.

Log In Sign Up. Wear rate properties of rocks like density, porosity, compressive of a material decreases almost linearly with hardness. Abrasion rate of any used in suffix like Nanotribology, Microtribology and natural stone can be expressed as the volume loss to the Biotribology.

Marble Samples used for Experimentation Table 2. There are different types of wear tests form of wear. Because at porosity then its abrasion resistance will be more. Regression analysis was carried out to investigate the relation between the abrasion resistance and the mechanical properties of marbles determined according to ASTM standards.

ASTM Test Machines

No Marble Name Class Colour Location smooth and their edges were rounded so that wear surface remain in complete contact with the rotating disc surface 1 Makarana Metamorphic White Doongari, Rajasthan contact. Compressive and tensile strengths are also traffic 2. Due to which deformation parameters like friction, impact or both are the main cause of abrasion. So, tribology describes many aspects of specimen surface area. The unusual chemical purity of Covelano White Marble also ensures that it produces no radiation.
