The raw materials used in the production of cement include limestone, chalk, shells, shale, clay, and silica sand. The mixture of these raw materials is then heated at high temperatures to form a solid rock-like substance, which is then powdered to obtain cement.

Sustainable Waste Management: A Case Study of Cement …

A cement plant consumes 3,000 to 6,500 MJ of fuel per tonne of clinker produced, depending on the raw materials and the process used [5]. Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil. As well as providing energy, some of these

Raw materials for cement manufacturing

Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influences its color.

How concrete is made - material, manufacture, making, how ...

Called admixtures, these additives can be used to increase the workability of a cement mixture still in the nonset state, the strength of cement after application, and the material's water tightness. Further, they can decrease the amount of water necessary to obtain workability and the amount of cement needed to create strong concrete.

ENVIRONMENTAL IMPACTS OF CEMENT PRODUCTION

The quantities of wastes used as raw materials in clinker production have more than doubled since 2001. In 2004, waste raw materials used in clinker production allowed the cement industry to make a direct saving of almost 14 million tonnes of conventional raw materials, which is equivalent to about 6,5 % of the natural raw materials needed.

CALIFORNIA CEMENT INDUSTRY

The U.S. cement industry has long been committed to minimizing emissions, waste, energy consumption, and the use of raw materials. For example, the cement industry began to address climate change in the mid-1990s—one of the first industries to do so. Over the past 40 years, U.S. cement manufacturers have reduced the amount of energy
