92. TYPES OF PORTLAND CEMENT. Portland cement is a closely controlled chemical combination of calcium, silicon, aluminum, iron and small amounts of other compounds, to which gypsum is added in the final grinding process to regulate the setting time of the concrete. Some of the raw materials used to manufacture
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the mid 19th century, and usually originates from limestone. It is a fine powder, produced by
?. Chapter Two. Types of Cement. The properties of cement during hydration vary according to: • Chemical composition. • Degree of fineness. It is possible to manufacture different types of cement by changing the percentages of their raw materials. Types of Cement. • Portland cement. • Natural cement. • Expansive cement.

For example Type IP(MS) is a portland-pozzolan cement with moderate sulfate resistance properties. Other special properties are designated by (HS), for high sulfate resistance; (A), for air-entraining cements; (MH) for moderate heat of hydration; and (LH) for low heat of hydration. Refer to ASTM C595 for more detail.
) such as air-entrainment, moderate sulfate resistance, or moderate heat of hydration may be specified by adding the suffixes A, MS. or MH. For example, an airrntraining portland blast-furnace slag cement that has moderate sulfate rt~iistaiice would be desipated as Type IS-A(MS).
Portland cement is the most common type of cement in general usage in many parts of the world, as it is a basic ingredient of concrete, mortar, stucco and most nonspecialty grout. It is a fine powder produced by grinding Portland cement clinker (the solid material produced by the cement kiln stage that has sintered into
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
