Understanding Cement and Its Importance

Concrete is a mixture of cement, aggregate( both coarse and fine), admixtures( chemical and mineral) and water used in foundation, RCC beams, columns slabs, etc. Technical Data used in the field explained in drilling courses in Islamabad.

The requirements of a high-quality concrete are essential for the adequate strength development required to bear various dead and live loads over it.

The quality of cement should necessary be checked from different field tests including the reading of the manufacturing date and the prescription of time of use. Ensuring presence of no lumps by crumbling the cement in your hands and a rough estimation of excessive silt content by forming cement balls and letting them dry in the sun( excessive sand in cement will create cracks and warping of cement balls). According to the visual appearance( the cement is greyish in colour with a tint of greenish shade in it) and using different types of cement according to the need( construction of dams and abutments use low heat cement. Some more details of drilling courses in Islamabad are as under.

Pozzolanic and Portland cement find a use for house construction of pillars, columns and roof slabs; rapid hardening white cement is utilised for whitewashing the walls.The most used type of cement in the world is the ordinary portland cement first invented by Joseph Aspirin, a worker; the cement soon became the most used in construction. However, the cement possesses moderate properties of the heat of hydration and reduced resistance to sulphate attack making it impossible to use for marine structure exposed to harsh conditions of attack of seawater. This incident forced scientists to develop the new type of cement to be utilised by the need of the work. When researchers were carried out, researchers found out four compounds formed after the reaction of argillaceous and siliceous materials which they named as Bogue compounds. It includes dicalcium silicate, tricalcium silicate, tricalcium aluminate and tetra calcium aluminium ferrite.
