White cement is same as that of grey Portland cement but the only differ is in the colour and fineness. This colour of this cement is determined by its raw materials and the process of manufacture. In this article we study about manufacture, properties, uses and difference of white cement. Contents:Manufacture of White CementFollowing Raw material […]
General. The total cultivable area in India is 1,945,355 km² (56.78% of it total land area), which is shrinking due to population pressures and rapid urbanisation. India has a total water surface area of 360,400 km². India's major mineral resources include Coal (4th largest reserves in the world), Iron ore, Manganese ore (7th largest reserve in the world as in 2013), Mica, Bauxite (5th ...
Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.
A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is only behind water .
Concrete manufacturers expect their raw material suppliers to supply a consistent, uniform product. At the cement production factory, the proportions of the various raw materials that go into cement must be checked to achieve a consistent kiln feed, and samples of the mix are frequently examined using X-ray fluorescence analysis.
A responsible raw materials policy must therefore create reliable framework conditions for sustainable supply of raw materials. This is the only way that companies will be able to obtain the planning and investment security required to continue to be able to cover requirements for top-quality cement-bound building materials in future.
Today, Ambuja Cement is proud to be 4 times water positive, as certified by external certification body DNV GL, making it India's leading water positive cement company. Our consistent efforts towards sustainable development have been recognized from various awarding bodies.

ALTERNATIVE RAW MATERIAL SOURCES FOR CEMENT PRODUCTION. Cement is a complete mixture of mineral substances that gradually harden when mixed with water. It is the product of the reaction of lime with the oxides of silica alumina and iron. It is used in the construction of industry as a blending material.
The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. The limestone is excavated from open cast mines after drilling and blasting and loaded onto dumpers ...
Raw Material Substitution. The cement industry already replaces some of its raw natural resources with waste and by-products from other industrial process Selected waste and by-products containing useful elements such as calcium, silica, alumina and iron can be used as raw materials in the kiln, replacing natural substances like clay, shale and limestone...

Cement manufacturing is the source of 5% of global CO2 emissions. The cement industry is a natural producer of CO2: 60% of emissions are due to the transformation of raw materials at high temperatures (the "decarbonation" of limestone), 40% result from the combustion required to heat the cement .

Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.
