• Portland Cement Specifiions [Types of Portland Cement ...

     · The distinct types of portland cement are defined through ASTM C15021: Standard Specifiion for Portland Cement, which distinguishes them by purpose. The standard types of portland cement are: Type I – for general purpose. Type IA – same as Type I, but when air entrainment is desired. Type II – for moderate sulfate resistance.

  • Cement mills and raw mills for high throughput rates

    Gases (air or hot gas) flow through this nozzle ring, take up the ground and dried material and convey it to the classifier where it is separated by the rotating wheel (rotor) into grits and fines. The grits fall back into the grinding zone whereas the fines leave the classifier with the gas flow for being separated in cyclones or a filter.

  • Concrete: Scientific Principles

    Concrete is not as likely to rot, corrode, or decay as other building materials. Concrete has the ability to be molded or cast into almost any desired shape. Building of the molds and casting can occur on the worksite which reduces costs. Concrete is a noncombustible material which makes it firesafe and able withstand high temperatures.
