Manufacturing process of cementWet Process Cement

 · As per World cement association concrete comes second only to water as the most used resource. China is the largest producer of cement with 53 and India follows with 8 with this production and is likely to be doubled in the next ten years. The basic raw materials used for the cement manufacturing process are limestone or chalk and shale or clay.

How Cement Is Made

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix 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.
