Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.

Chemical Composition of Cement - University of Babylon

Chemical Composition of Cement The raw materials used for the manufacture of cement consist mainly of lime, silica, alumina and iron oxide. These oxides interact with one another in the kiln at high temperature to form more complex compounds. The relative proportions of these oxide compositions are responsible

Uses of Cement - The Constructor

The ingredients of cement concrete are cement, fine aggregate, coarse aggregate and water respectively. In general, ordinary Portland cement is used to prepare concrete. But for special cases or based on different circumstances many types of cements like rapid hardening cement, high alumina cement etc. are discovered.

How concrete block is made - material, manufacture, used ...

The concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel. This produces a light gray block with a fine surface texture and a high compressive strength. A typical concrete block weighs 38-43 lb (17.2-19.5 kg).

8 Main Cement Ingredients & Their Functions - Civil ...

The excessive presence of lime causes the cement to expand and disintegrate. Silica : Silicon dioxide is known as silica, chemical formula SiO 2. The sufficient quantity of silica should be present in cement to dicalcium and tricalcium silicate. Silica imparts strength to cement. Silica usually presents to the extent of about 30 percent cement.

Deep decarbonisation of cement production | News | gasworld

Changes to the way concrete is made and used will also support decarbonisation. For example, fly-ash from coal combustion can partially replace clinker in cement. Less clinker production means reduced carbon dioxide emissions. Binding carbon dioxide into concrete during the curing process is also a way to utilise captured carbon dioxide.
