  • Portland Cement Concrete an overview | ScienceDirect Topics

    Portland cement, as the most important binder material of concrete, is the main component that determines the overall properties of the concrete infrastructures With the development of global industrialization, the needs for cement concrete materials keep increasing every year, especially in many developing countries As a result, the amount of Portland cement production increases annuallyCEMEX Portland is produced by burning a precisely specified mixture of raw materials containing lime, silica, alumina and small quantities of other materials to form a clinker The clinker, together with calcium sulfate to control setting, is then ground to produce cement of the required fineness Up to 5% of minor additional constituents (typically, limestone, fly ash or granulatedCEM1 Portland Cement | CEMEX UKPortland cement is used to make almost all concrete It is also the principal cement used in most masonry mortars and renders The Mastercrete Cement contains special additives which allows for a better performance Enhanced resistance to freeze/thaw attack reducing cracking in your concreteis also a lighter colour than normal cement Mastercrete is a quality assured cement with independentPortland Cement 25kg Buildingmaterialscouk
