Dimension stone

Marble and other limestones are used in relatively small tonnages as dimension stone for ornamental purposes such as facing buildings and tombstones.

Limestone Production. Because more than 99% of U.S. limestone is sold or used as cmshed and broken stone, rather than dimension-stone, most of the description of limestone s extraction and processing herein focuses on the former (Fig. 4). Most stone is obtained by open-pit quarrying methods. Underground mining is pursued by some important operations, but the toimage quarried exceeds that mined by nearly 20-fold. There is, however, a slight trend toward increased mining which should continue. 

Cemented tungsten carbides also find use as a support for polycrystalline diamond (PCD) cutting tips, or as a matrix alloy with cobalt, nickel, copper, and iron, ia which diamond particles are embedded. These tools are employed ia a variety of iadustries including mineral exploration and development oil and gas exploration and production and concrete, asphalt, and dimension stone cutting. 

Building stone (dimension stone) is usually cut from the quarry face by means of a wire saw. Explosives are used only for clearing overburden or to remove obstacles. The process of quarrying is analogous to obtaining coal from opencast sites where the coal is at or near the surface of the ground. Under wet conditions,...

This cycle is typical for the mining of narrow, steeply dipping veins (typical of metal ores), and for massive deposits of limestone, salt, and dimension stone, where the vertical extent of the valuable mineral is 6 meters or higher. 

In this paper, we describe an onsite weathering experiment designed to identify acid-rain increased dissolution of carbonate rock. This experiment is based on the measurement of the change in rainfall-runoff composition from the interaction of a rock surface with incident acid rain 2. The experiment involves conducting long-term exposures of two commercially and culturally important calcium carbonate dimension stones (i.e., Indiana Limestone (commercial name for Salem Limestone) and Vermont Marble (commercial name for Shelburne Marble)) (3-5). This technique appears to give a direct measurement of the chemical dissolution of carbonate rock from the combined reactions of wet and dry deposition. Preliminary results from the initial months of onsite operation are presented to illustrate the technique. 

Over the centuries, limestone has been used extensively as an aggregate in building and construction. It has been used as aggregate in lime-based concrete since Roman times, and, more recently, in cement-based concrete. Although limestone cannot readily be dressed, it has been used extensively in building in both the rough-hewn form and as cut dimension stone. 

A small tonnage of limestone is used in the production of dimension stone. The process is outlined in section 4.7. 

Dimension stone is stone which has been cut into blocks of specific dimensions.

An important part of the world s cultural heritage is represented by stone monuments. This enormous artistio legacy includes historical and modem buildings as well as decorative stone stmctures, individual monuments and an arr of monuments constmcted with dimension stones or earved from bedroek, such as sculptures and/or artefacts of different size and shape. Many stone types have been used for eonstracting monuments. Due to their...
