Did you know that in fact there are various types of cement and types according to their function and usefulness, well for those of you who do not know should continue reading the following simple article , cement is a building material that practically can not be replaced with other materials. Cement is the glue hydraulic construction materials, means it will be adhesion when mixed with water.
The basic ingredients of cement in general there are 3 kinds of clinker / slag (70% to 95%, is processed by burning limestone, silica sand , iron sand and clay), gypsum (about 5%, as a hardening agent pelambat) and third material such as limestone, pozzolan, fly ash, and others. If the third element is not more than about 3% are generally still meet quality type 1 or OPC (Ordinary Portland Cement). However, when the content of material third higher by about 25% at the maximum, then the cement will change the type to PCC (Portland Composite Cement).
Type Cement according to Indonesian National Standards (SNI), among others:
1. White Portland Cement
used for job completion (finishing), as a filler or fillers. Cement is made from a type of primary material calcite (calcite) pure limestone.
2. Portland cement Pozolan
This product is more appropriately used for public buildings and buildings that require endurance sulfate and heat of hydration medium, such as: bridges, highways, housing, docks, concrete mass, dams, irrigation and foundation plate full .
3. Portland Cement
is the most common type of cement in general use around the world because it is the basic ingredient of concrete, and stucco.
4. Mixed Portland Cement
a hydraulic binder results of grinding together of slag Portland cement and gypsum with one or more inorganic materials that are not reacting (inert).
5. Cement Mansonry
Cement is more appropriately used for residential construction of buildings, roads and irrigation. Can also be used as raw material for the manufacture of concrete roof tiles, paving blocks, tiles and other building materials.
6. Portland Composite Cement
used for buildings in general, together with the use of Portland Cement Type I with the same compressive strength. PCC has a heat of hydration lower during the cooling process compared with Portland Cement Type I, so that the process will be easier and produce a surface of concrete / plaster denser and finer.
Cement Portland / Ordinary Portland Cement (OPC) there are 5 types:
1. Portland Cement Type I (Ordinary Portland Cement)
Portland cement type I is a type of cement that is most needed by the public and can be used for all applications that do not require special requirements. For example, when a homeowner or a mason who was working on a project or renovate homes will buy cement in the shop building, they just call cement, without specifying what type of cement should be used or matched to the neighborhoods they are. among others: building, residential, high-rise buildings, bridges, runways and highways.
2. Portland Cement Type II (Moderate sulfate resistance)
Ordinary Portland Cement Type II is the heat of hydration of cement with moderate or below the Type I Portland cement and sulphate resistant. Cement is suitable for areas that have the weather with a temperature high enough and the drainage structure. Portland cement type II is recommended for use in buildings such as dams, docks and heavy foundation that marked the columns and where the low hydration process is also a major consideration.
3. Portland Cement Type III (High Early Strength Portland Cement)
this type gained great strength in a short time, so it can be used to repair concrete buildings that need to be used or that the reference should immediately be removed. It also can be used in areas that have lower temperatures, especially in areas that have winter. Usefulness manufacture of concrete road, airstrip, high-level buildings, the buildings in the water that does not require resistance to sulphate.
4. Portland Cement Type IV (Low Heat Of Hydration)
Type of cement with low heat of hydration. This type of cement used for construction purposes, which require a rise in the number and the heat should be minimized. Therefore, this type of cement will have a strong level of concrete at a slower pace than Portland cement type I like this type are used for massive concrete structures such as dams big gravity in which the temperature rise due to the heat generated during the curing process is a critical factor. Suitable for hot climes.
5. Portland Cement Type V (Sulfate Resistance Cement)
Portland cement is in use requires a high resistance to sulphate. Suitable for the manufacture of concrete on the land and water areas that have a high content of sulfate salts. It is suitable for the installation of sewage treatment plant, the construction of water, bridges, tunnels, ports and nuclear power plants.
