Sedimentary rocks are formed by fragmenting existing rocks and cementing the fragments together to form a new rock. Sandstone is perhaps the most widely recognized sedimentary stone. Sandstone is made up of sand-sized rock fragments and individual minerals that have been broken down from older rocks. Based on our experiences at the …

To minimize the risk of cracks, fissures and other aesthetic damage to the stone, fabricators use a process known at "wire sawing" to gently separate the marble (Figures 1a and 1b). First, two 3-inch wide holes are drilled perpendicularly to each other. Once the holes connect, a heavy-duty wire embedded with artificial diamonds is fed …

folding. The suitability of sandstone for aggregate use depends on its strength, porosity and durability (Fig. 1). Many types of sandstone are too porous and weak to be used other than as sources of constructional fill. In general, older more indurated sandstone exhibit higher strengths and are suitable for more demanding aggregate uses.
