  • Portland cement - Wikipedia

    Portland cement - Wikipedia

    2019-11-19Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.It was developed from other types of hydraulic lime in England in the late 19th century by Joseph Aspdin, and usually originates from limestone.It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker ...

  • Watercement ratio - Wikipedia

    Watercement ratio - Wikipedia

    2019-11-5The watercement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. A lower ratio leads to higher strength and durability, but may make the mix difficult to work with and form. Workability can be resolved with the use of plasticizers or super-plasticizers. Often, the ratio refers to the ratio of water ...

    2000-3-17This is a fluxing agent which reduces the melting temperature of the raw materials in the kiln from 3,000 o F to 2,600 o F. It hydrates rapidly, but does not contribute much to strength of the cement paste. By mixing these compounds appropriately, manufacturers can produce different types of cement to suit several construction environments.
