Ordinary Portland Cement -Definition,Composition,Uses

Sep 13,2019 Composition of cement#0183;Ordinary Portland Cement (OPC) Ordinary Portland Cement (OPC) is one of the most widely used types of Portland cement.; The name Portland Cement was named by Joseph Aspdin in 1824 due to its similarity in color and its quality when it hardens like Portland stone.; Portland Cement is a fine powder that when mixed with water becomes the binding material that holds aggregates together in concrete.OIL WELL CEMENT Lafarge - Cement,concrete andOil well cement must also be designed and tested to perform with specific admixtures that are added to the slurry mix in order to achieve the desired thickening timeand rheology.The four most commonly used well cement types are Class A,Class C,Class G,and Class H.How Concrete is Made - Portland Cement AssociationThe longer the concrete is kept moist,the stronger and more durable it will become.The rate of hardening depends upon the composition and fineness of the cement,the mix proportions,and the moisture and temperature conditions.Concrete continues to get stronger as it gets older.

In the concrete compositions,360 kg/m 3 PC-A cement was used; the maximum grain size of the river gravel was 31.5 mm.Because a major objective was to realise highly fluid mixtures,the fresh concrete slumps were 230 plus-minus 40 mm.This resulted in a water to cement ratio of 0.32 for the mixtures containing fillers and 0.35 for the reference mixture (no filler added).Concrete Composition Hydration process of cementMar 29,2020 Composition of cement#0183;Concrete defines as a composition of construction material cement,fine aggregate i.e.sand,coarse aggregate,and water which harden with time..Generally,if the concrete is used with steel than it is called as a Reinforced Cement Concrete..In addition to this,We can use also Admixture in concrete to change its chemical and mechanical properties.Composition Of Cement Clinker Expert CivilComposition of Cement Clinker The various constituents combine in burning and form cement clinker.The compounds formed in the burning process have the properties of setting and hardening in the presence of water.They are known as Bogue compounds after the name of Bogue who identified them.
