AnagramsFrom Wiktionary under the GNU Free Documentation License. Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO3). The deposition of limestone strata is often a by-product and indicator of biological activity in the geologic record. Calcium (along with nitrogen, phosphorus, and potassium) is a key mineral to plant nutrition: soils overlying limestone bedrock tend to be pre-fertilized with calcium. Limestone is an important stone for masonry and architecture, vying with only granite and sandstone to be the most commonly used architectural stone. Limestone is a key ingredient of quicklime, mortar, cement, and concrete. The solubility of limestone in water and weak acid solutions leads to important phenomena. Regions overlying limestone bedrock tend to have fewer visible groundwater sources (ponds and streams), as surface water easily drains downward through cracks in the limestone. While draining, water slowly (over thousands or millions of years) enlarges these cracks; dissolving the calcium-carbonate and carrying it away in solution. Most well-known natural cave systems are through limestone bedrock. From Wikipedia under the

My son has to do a project for school where he has to Investigate the minerals found in Limestone, determine the edible parts, and create an edible limestone rock. What edible minerals are in limestone? Asked by Love S - Sat Mar 21 17:29:18 2009 - - 2 Answers - 0 Comments A. Please understand that LIMEstone has nothing to do with lime the fruit. Minerals that are present in rocks are naturally occurring inorganic chemicals which may or may not be ingested into our bodies with harmful or with beneficial side effects. Limestone is composed almost entirely of the mineral calcite which, chemically is Calcium carbonate. If one ate SMALL amounts of powdered calcium carbonate it would probably produce a lot of gas as it reacted with the fluids in the stomach but would leave a person otherwise unharmed. In CERTAIN parts of the world, limestone is associated with barytes (barium sulphate), fluorspar (calcium fluoride), brucite (magnesium oxide) or periclase (magnesium hydroxide). Calcium fluoride, in small… [cont.] Answered by Tashkent T - Sat Mar 21 19:14:00 2009 I need tips on how to lay limestone blocks for a square column on my porch? Q.

I've never used mortar and would like some help on how to do this in the easiest way possible. Asked by jonthebrute - Thu Nov 9 18:08:27 2006 - - 3 Answers - 0 Comments A. I have layed lots of block , brick, and stone. I think mortar should be used. Using mortar you can build staight up regardless of how poorly the stone fits together. The biggest mistake rookies usually make is mixing the mortar too wet. It should be the consistency of wet beach sand. Always slop double the motar needed on before setting the next layer. Press the stone down into position and the excess will squeeze out. Polish off the joint with a wet metal tool for nice joint appearance. limit the work to 4 or 5 stone layers and let it set overnite before adding more layers Answered by morris - Thu Nov 9 19:50:21 2006 How is glass, cement and concrete made out of limestone?
Q. I know that you can make glass, concrete and cement out of limestone, but how? Asked by METAL - Thu Oct 2 06:39:55 2008 - - 3 Answers - 0 Comments A. I have never seen glass made from limestone. Limestone (Calcium Carbonate) is one of the main raw materials for making cement. It is reacted with other materials containing sources of silica, alumina and iron in a kiln (heated to 2500F). The resulting compound is ground (with other minor compounds such as gypsum) to produce cement. Cement is mixed with an aggregate and water to produce concrete.
