  • Measurement of the heat of hydration of cement -

    The traditional method by which the heat of hydration of cement has been determined in most European countries has been by measurement of the heat of solution. Initially developed for Portland cements, this method requires a high degree of operator competence to achieve reliable results. When used to determine the heat of hydration for composite cements there were practical difficulties with ...

  • The cement kiln

    Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the hot end where it eventually drops out and cools ...

  • Cement - Wikipedia

    A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is only behind water as ...

  • Loss on ignition - Wikipedia

    Loss on ignition (LOI) is a test used in inorganic analytical chemistry and soil science, particularly in the analysis of minerals and the chemical makeup of soil. It consists of strongly heating a sample of the material at a specified temperature, allowing volatile substances to escape, until its mass ceases to change.This may be done in air, or in some other reactive or inert atmosphere.
