As sandstone is a natural material,it costs a little more than concrete. The cost of finding the sandstone and breaking the stone into smaller pieces adds to the overall cost. Does Obsidian exist? obsidian, igneous rock occurring as anatural glass formed by the rapid cooling of viscous lava ...
These are composed of fragments of rocks which were transported from the source by mechanical means, deposited and subsequently compacted,e.g.sandstone, conglomerate and shale. Chemical sedimentary rocks: These is formed when chemicals dissolved from the rocks are carried in solution to other areas w...

Sandstone is an example of a sedimentary rock. It formed over eons as small particles bound together with mud under pressure, and unlike igneous rocks, like granite, it can be somewhat fragile. It has attractive coloration ranging from brown to tannish pink, and it has many utilitarian and d...
aWe knew that it was formed from sandstone that solidified somewhere between 150 and 300 million years ago. Before it solidified, it was just regular sand. Essentially it was part of a vast desert. And until just recently, most of us thought the sand had come from an ancient mountain range...
Sandstone is a sedimentary, rock-like material formed under pressure and composed of sand particles held together by a cementing material such as calcium carbonate. A few sandstones are composed of almost pure quartz particles and are the source of the silicon used to make semiconductor silicon ...
