  • How Portland Cement is Made Manufacturing Process of

    Portland cement can be made by following two different processesa dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85 of portland cement. The materials that are commonly used are limestone shells chalk shale clay slate silica sand and iron ore. Since limestone is the main

  • CementThe major cements composition and properties

    Waterproof cement is the name given to a portland cement to which a water-repellent agent has been added. Hydrophobic cement is obtained by grinding portland cement clinker with a film-forming substance such as oleic acid in order to reduce the rate of deterioration when the cement is stored under unfavourable conditions.
