Raw Materials Of Cement Production

At the cement production factory the proportions of the various raw materials that go into cement must be checked to achieve a consistent kiln feed and samples of the mix are frequently examined using x-ray fluorescence analysis the strength of concrete is probably the most important property that must be tested to comply with specifications.
