An Experimental Study on Marble waste used in Paver Blocks

The first forms of road transport involved animals, such as horses (domesticated in the 4th or the 3rd millennium BCE), oxen (from about 8000 BCE) [1] or humans carrying goods over dirt tracks that often followed game trails. Many early civilizations, including Mesopotamia and the Indus Valley Civilization, constructed paved roads. In classical antiquity, the Persian and Roman empires built stone-paved roads to allow armies to travel quickly. Deep roadbeds of crushed stone underneath kept such roads dry. The medieval Caliphate later built tar-paved roads. A paver is a paving stone, tile, [6] brick [7] or brick-like piece of concrete commonly used as exterior flooring. They are applied by pouring a standard concrete foundation, spreading sand on top, and then laying the pavers in the desired pattern. No actual adhesive or retaining method is used other than the weight of the paver itself except edging. Pavers can be used to make roads, driveways, patios, walkways and other outdoor platforms. This study investigate the possible way for constructing the pavement blocks by using wastes. The experiment were conducted with the of proper utilization of the solid waste in construction of paver blocks without affecting the various mechanical properties such as compressive strength, flexure strength and split tensile strength. The waste which we are going to select is the waste generated by marble stone quarrying or at the time of its dressing. The paver blocks were constructed by using the waste marble products after replacing the coarse aggregate by some defined percentage. these blocks were tested by different tests like compressive strength test, flexural strength test, and split tensile strength test. The compressive strength found to be in between 47.35 N/mm2 to 44.98N/mm2. But we observed that up to 40 % replacement of coarse aggregate with marble stone generally does not shows any major difference. The replacement of coarse aggregate with the marble stone generally does not affects the flexural strength of the paver blocks. In the same manner the split tensile strength of the paver blocks does not shows any effect by the replacement of coarse aggregate with marble stones. The approximate value is found to be 46.5 N/mm2. Based on these experiment we concluded that the waste generated by the marble stone can be used as an alternative for the natural crushed stone used in paver blocks as the compressive strength, flexural strength and the split tensile strength of the testing blocks does not shown any major difference with its original standard mix paver blocks.
