All about Limestone Limestone is one of the most common types of rock found on the surface of the Earth. About 10% of the land surface of our planet is made of limestone or similar types of rock; while around 25% of the world's population either live on or take their water from limestone.
Limestone has low porosity; it is weather resistant and has a density of between 2.5 and 2.7 kg/cm3. It has a hardness of between 3 and 4 on Moh's Scale and a water absorption of less than 1 percent. Limestone is a very compact rock that takes polish very well.
Limestone deposits are of sedimentary origin and exist in all the geological sequences from Pre-Cambrian to Recent except in Gondwana. 75 per cent Limestone is used in cement industry, 16 per cent in iron and steel industry [It acts as flux] and 4 per cent in the chemical industries. Rest of the limestone is used in paper, sugar, fertilizers, etc.
Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.
Limestone is one of the most versatile substances and has a lot of different applications that can benefit our livelihood. While our primary interest is how limestone can be used as a fertilizer for crops, lawns, and gardens, it adds depth to our understanding to consider the many uses other uses that pulverized limestone .

There are various physical properties of Limestone like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Limestone rock are vital in determining its Limestone Texture and Limestone Uses. Hardness and Strength of Limestone. The physical properties of Limestone depend on its ...
Sedimentary rocks are the most common rock types which are freely exposed on the earth's surface. They are formed from other rock materials since they are made up from the buildup of weathered and eroded pre-existing rocks. The weathering, erosion and the eventual compaction of igneous, metamorphic or formerly structured sedimentary rocks among other biological sedimentations leads .
From Early Dynastic times onward, limestone was the material of choice for pyramids, mastaba tombs, and temples within the limestone region. From the late Middle Kingdom onward, sandstone was used for all temples within the sandstone region as well as many of those in the southern part of the limestone .
limestone, sedimentary rock [1] wholly or in large part composed of calcium carbonate [2]. It is ordinarily white but may be colored by impurities, iron oxide making it brown, yellow, or red and carbon making it blue, black, or gray. The texture varies from coarse to fine.
Limestone is a type of rock that is made up of bits of animal shells. Over millions of years these shells collected on the ocean floor. As layers of shells and mud built up, the lower layers slowly hardened into limestone.
Also, the metals and minerals found in rock play an important role in our life. Get to know all the Limestone Uses. We have provided you with all information about Limestone rock here. Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of .
Chalk, soft, fine-grained, easily pulverized, white-to-grayish variety of limestone. Chalk is composed of the shells of such minute marine organisms as foraminifera, coccoliths, and rhabdoliths. The purest varieties contain up to 99 percent calcium carbonate in the form of the mineral calcite. The
Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
Limestone Facts. Limestone is a sedimentary rock that contains at least 50% calcium carbonate (CaCO3). Because sedimentary rocks are made of various types of sediments, the other 50% of a limestone rock could be virtually any other mineral. Limestone originates in wet areas which mean it could also be composed of shells and waste matter from ...
Fun Facts about Sedimentary Rocks for Kids. Sandstone is made from grains of sand that have melded together over time, or lithified. Sedimentary rock often contains fossils of plants and animals millions of years old. The mudstone cliffs along the southern coast of .
Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone.
Limestone is a collective term for a group of sedimentary rocks that consist of at least 50 percent calcite, a mineral formed of calcium carbonate. If some of the calcium becomes replaced by magnesium, the resulting calcium magnesium carbonate rock is called dolomitic limestone. ... Physical Characteristics of Limestone
Uses of Limestone. Limestone has many industrial uses and can be used as mined or processed into a wide variety of products. It is the raw material for a large variety of construction, agricultural, environmental, and industrial materials. Limestone is used in construction almost everywhere. In 2007, crushed limestone was 68% of all crushed ...
This is a list of types of limestone arranged according to location. It includes both formal stratigraphic unit names and less formal designations.

Main Uses of Limestone: In Missouri, limestone of all kinds is used mainly for aggregate (aka "gravel") that is produced by crushing and screen-sizing limestone quarry rock. The aggregate is used in concrete, for road surfacing (with or without asphalt or tar binder), and for foundation support beneath weight-bearing structures.
