3.8 Types of Portland cement. The ASTM has designated five types of portland cement, designated Types I-V. Physically and chemically, these cement types differ primarily in their content of C3A and in their fineness. In terms of performance, they differ primarily in the rate of early hydration and in their ability to resist sulfate attack.
What are the different types of cement - The following are the types of cement that are used in construction works: Rapid Hardening Cement It is used in concrete where form works are removed at an early stage. Quick setting cement It is used in works to be completed in very short period and concreting in static and running water.

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.
SPECIAL TYPES OF CONCRETE 5-694.800 5-694.810 GENERAL In the general use of the word concrete, the idea implied is the conventional placement of the material within formed areas where the material will rem ain. There are, however, m any variations of this procedure and a few are listed below.
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.
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.
