This review collects categorizes and summarizes the use of different types of mining waste in construction materials including concrete (cement sand and aggregate) fired bricks (clay) and backfill materials (soil). This paper presents an overview of the characteristics of mining waste and its use in construction materials particularly in
considered for use in cement and dolomitic lime operations where there is evidence of energy or mineral content recovery in recognition of the Waste Hierarchy 4. a new material is identified for recovery in cement or dolomitic lime installations then an assessment and introduction process will be followed.

types of cement and their uses ppt 1. Natural Cement. Natural Cement is manufactured from crushed stone with 20 to 40 clay content and remaining lime. mixed carbonate magnesia. It holds brown in colour and sets rapidly when mixed with water. USES It is mostly used for the restoration of old buildings and monuments.
3. Waste Material Based Concrete • Three types of wastes • Organic Waste • Inorganic Waste (Urban Waste) • Industrial Waste. 4. Organic Waste • It is Plant originated namely saw dust coconut pith rice husk wheat husk groundnut husk etc. • Rice Husk • Produced in rice mills each tonne of paddy produces about 200 Kg of husk.

A high weight loss on ignition of a cement sample (between 900 to 1000ºC) is an indication of prehydration and carbonation which may be caused by Improper and prolonged storage Adulteration during transport and transfer Loss on ignition values range between 0 to 3 9.
Mineral ore is a mineral deposit mixed with. rocks and it contains enough of a metal to. permit it to be extracted and sold at a profit. 6. USES OF MINERALS. Raw material in industries (iron) Diamonds hardest mineral can be used for various. industrial purposes (drill bits coating for.
• The cement industry coprocesses waste as a substitute for primary raw materials and fossil fuels. It offers a safe and sound solution for society the environment and the cement industry by substituting non renewable resources with societal waste under strictly controlled conditions. The use of alternative raw materials also has numerous
Alternative Fuels in Cement Manufacture. 2009 9 21 cement and concrete in co operation with member associations and the Cement manufacturing is a major mineral commodity industry In 1995 the world production of cement was 1420 million tonnes In the European Union cement is wastes as raw materials for clinker production and as alternative fuels

CRISTINA MARTÍN SERRANO. 2. GENERAL INFORMATION ABOUT CEMENT INDUSTRY. Cement is a basic material for building and civil. engineering construction. Cement is a finely ground nonmetallic inorganic powder when mixed with water forms a. paste that sets and hardens. World cement production has grown steadily since.
SolidLiquid Separation and Waste Treatment 10. Other Methods of Mineral Extraction 11. Disposal of Solid Wastes and Waste Water Treatment 12. Conclusion In the preparation of nonmeta llic mineral resources such as cement rocks for recovery of coarsegrained highdensity mineral prior to further size reduction stage.
Reusing and recycling of mine wastes is also possible. Adsorbent production is an alternative way to utilization of mining wastes for wastewater cleaning. Adsorption processes are being widely
Biomining is mineral processing with microbes. Biomining is the process of using microorganisms (microbes) to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals. Valuable metals are commonly bound up in solid minerals.
Waste Heat Recovery Power Plants contribute significantly to the electrical energy saving (to the tune of 25 ). The reduction in CO 2 emission makes it environmental friendly. Installation of the waste heat recovery plant has to be tackled as a system approach rather than considering cement plant and WHRPP operations independently.
