Cement Production - an overview ScienceDirect Topics

The production of cement is an energy-intensive process using primarily fossil fuel sources. Cement comprises about 10% of a typical concrete mix but accounts for 92% of its energy demand. Cement production requires the pyroprocessing of large quantities of raw materials in large kilns at high and sustained temperatures to produce clinker. An ...

2024年6月25日  Concrete is characterized by the type of aggregate or cement used, by the specific qualities it manifests, or by the methods used to produce it. In ordinary structural concrete, the character of the concrete is largely determined by a water-to-cement ratio. The lower the water content, all else being equal, the stronger the concrete.
