Cement is the major raw material used in any construction. Therefore quality of cement must be checked before using it as a building material. Following tests can be performed on cement in laboratory to check its quality.
Regular concrete can typically withstand a pressure from about 10 MPa (1450 psi) to 40 MPa (5800 psi), with lighter duty uses such as blinding concrete having a much lower MPa rating than structural concrete. Many types of pre-mixed concrete are available which include powdered cement mixed with an aggregate, needing only water.
Types of cement. Cement is a binding material used to bind different type of construction materials together. It is formed from argillaceous, siliceous, calcareous etc. By twisting this internal mix ratio and by altering the chemical inputs, special types of cement can be produced according to the needs.

Concrete and Cement are the most widely used building materials in the construction industry for over 100 years. Over the years, this construction material has been enhanced and developed to fit to the usage and requirements at site. Several researches are happening around this topic to increase the durability, strength and performance of this building material.
Types of Cement 8. Coloured Cement: White Cement – IS 8042: 1989 For manufacturing various coloured cements either white cement or grey Portland cement is used as a base. The use of white cement as a base is costly. With the use of grey cement only red or brown cement can be produced. 9.
The plunger will penetrate the cement up to a certain depth depending on the consistency. A cement is said to have a normal consistency when the plunger penetrates 10±1 mm. Strength of Cement. Three types of strength of cement are measured – compressive, tensile and flexural.
