We first discusscementproduction and special nomenclature used bycementindustrialists in expressing the composition of theircementproducts. We revealdifferent types of cementproducts, their compositions, properties, and typical uses. Wherever possible, we tend to give reasons as to why a particularcement typeis more suitable for a given purpose than othertypes.

Composition of cement. IntroductionPortland cementgets its strength from chemical reactions between thecementand water. The process is known as hydration.This is a complex process that is best understood by first understanding the chemicalcomposition of cement.

It contains silica, alumina,limeand other minerals invariousproportions and, in modern practice, is more commonly used as anadditivein Portlandcementconcretes. Historically, forge scale and iron-rich slag, known as minion, were also used.

Sometimes, other mineraladditivessuch as groundlimestone, fly ash, or slag, are also added during the final stagesof cementmanufacture, even for ordinary Portlandcement. In fact, most cements in India have fly ash or groundlimestoneas a minoradditive(BIS permits up to 5% performance improver).

Thecement manufacturing processstarts from the mining of raw materials that are used incementmanufacturing, mainlylimestoneand clays. Alimestonequarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. Thelimestoneis excavated from open cast mines after drilling and blasting and loaded onto dumpers ...

Blendedcementcan be defined as uniform mix of ordinary Portlandcement(OPC) and blending materials such as silica fumes, fly ash,limestoneand slag to enhance its propertiesfor differentuses. Blendedcementcan improve workability, strength, durability and chemical resistanceof concrete.
