Portland cement can be made by following two different processes – a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.

There are lots of environmental impacts of Cement on our ecology. One of the major problems is emission of CO2 from the Cement industry. It is found that world yearly billion tons production of cement covers 7% of carbon dioxide''s yearly production. As CO2 is harmful for human health and also for the wild life. It causes many respiratory problems like asthma, bronchitis, and nasal infections.
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to readymix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

Cement Cement Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
OPC typically means Ordinary Portland Cement. This is standard concrete used for many purposes. PPC mean Pozzolanic PortlandCement. Pozzolans are siliceous material than can be added to concrete mixtures, potentially lower the mix cost without harming the performance characteristics.
This process can vary depending on the mixture as well as the desired result. Ordinary Portland Cement is the most prevalent because of the readily available raw materials in the area where it is produced. For this reason, OPC is also an ideal option for cement needs throughout the world today as the costs of producing it are very low without ...

Having a higher percentage of C 3 A, cement sets quickly, and releases a high heat of hydration. C 3 S gives the cement its initial strength, and makes it harden rapidly. On the other hand, C 4 AF has little to do with strength, but imparts the gray color to ordinary Portland cement. ''Heat of hydration'' is the term used to describe the heat released when cement reacts with water during the ...
