Limestone i s a sedimentary rock that is primarily composed of Calcium carbonate in the form of calcite mineral. It forms mostly in the clear, warm and shallow marine water accumulates in the form of organic debris as coral, shells, algal or fecal deposits.
National's NatCrete is specifically designed to enhance the properties of concrete and masonry block. NatCrete can be used as a replacement for cement or slag. It is recognized by ACI, ASTM, ODOT, OAIMA and Ohio Concrete. NatCrete is lighter in color than Portland cement, slag and fly ash, resulting in more desirable color of exterior concrete.
To the southeast of this area, the rocks and limestone were unfit for cement making, and to the northwest there was an abundance of shales and slates. These deposits proved to be suitable, and Saylor turned out the first portland cement in 1875.
In fact, many 'limestone' deposits used for cement manufacture are really lowgrade marble. This is especially evident if the deposit contains significant volcanic intrusions or other signs of volcanic activity. Also, some cement plants use waste from marble mines as a secondary raw material.

The geographical distribution of limestone deposits in India is also not uniform. Some of the States do not have any limestone deposits. It has been observed that more than 95 per cent of cement grade limestone deposits are concentrated in 10 states, although the cement grade limestone .
Portland cement, lime, and brick are also manufactured. Portland cement is produced from lowmagnesium limestone, lime from limestone and dolomite, and brick from clay and shale. Production and use of industrial minerals have been and will continue to be a key component of the state's economy.

Dec 03, 2013· Limestone vs Dolomite Both limestone and dolomite are types of rock made of carbonate residues. The patterns of the way they behave chemically are almost the same with varied intensities. However, the structure and the formation of these rocks are quite different. Limestone Limestone mainly consists of two types of minerals; namely, calcite and aragonite.
Limestone is a tailored stone that conveys a traditional formality. It is a handdressed, chiseled textured stone roughhewn into a rectangular ashlar profile. This stone is medium in scale and ranges from 2″ to 8″ in height and 4″ to 17″ in length, and has an average stone size of 6″ by 12″.

Limestone around Waitomo ranges from 40% to calcite (calcium carbonate). The rest of the limestone is made up of volcanic fallout and local basement rocks carried by rivers into the ancient sea. About 8090% of the calcite is composed of skeletal fragments, while the rest is a calcite cement that was naturally precipitated form the sea.
