Did you know that in fact there are different types of cement and type depending on the function and the utility, although for those of you who do not know must continue to read the article following simple, concrete is a building material that can hardly be replaced by other materials. The hydraulic cement is adhesive construction materials, means that it will adhesion when mixed with water.
The cement-based ingredients in general there are 3 types of clinker / slag (70% to 95%, is treated by burning limestone, silica sand, sand iron and clay ), gypsum (about 5%, as pelambat curing agent) and a third material such as limestone, pozzolans, fly ash and other. If the third element is not more than about 3% are generally still meet the quality type 1 or OPC (Ordinary Portland Cement). However, when the content of third upper material of about 25% maximum, then the cement will change the type of PCC (Portland Composite Cement).
type of cement according to national standards of Indonesia (SNI), among others:
1. Portland cement white
used for completion of the work (finishing), as filler or fillers. This type of cement is made from Calcite main material (calcite), the pure limestone.
2. Portland cement Pozolan
This product is more appropriately used for buildings and buildings that require endurance sulfate and heat of hydration medium public, such as: bridges, roads, housing, docks, mass concrete, dams, irrigation and complete foundation plate.
3. Portland Cement
is the most common type of general-purpose cement in the world because it is the basic ingredient of concrete, and stucco .
4. Mixed Portland cement
a hydraulic cylinder grinding binder of results as well as Portland cement clinker and gypsum with one or more inorganic materials that are not react (inert).
5. Cement masonry
Cement is more appropriately used for residential construction of buildings, roads and irrigation. Can also be used as raw material for the manufacture of roof tiles of concrete, paving stones, tiles and other building materials.
6. Portland Cement Composite
used for buildings in general, and the use of Portland cement type I with the same compressive strength. CPC has a lower heat of hydration during the process of cooling compared with Portland cement type I, so the process will be easier and produce a concrete surface / denser and fine plaster.
Portland cement / 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 an owner or a mason who was working on a project or renovate houses will buy cement in the workshop building, they call simply the cement, without specifying what type of cement should be used or adapted to neighborhoods where they are. inter alia :. building, residential, high-rise buildings, bridges, trails and roads
2. Portland Cement Type II (moderate resistance to sulfate)
The ordinary Portland cement type II is the heat of hydration of cement or moderate below the Portland cement type I and sulphate resistant. Cement is suitable for areas which have time with a sufficiently high temperature and the drainage structure. Portland cement type II is recommended for use in buildings such as dams, docks and heavy foundations that marked where the columns and the low hydration process is also an important 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 to be used or that the reference should be removed immediately. It can also be used in areas which have lower temperatures, particularly in areas where the winter. manufacturing concrete road Usefulness of the runway, the high-level buildings, buildings in water which does not require resistance to sulphate.
4. Portland cement type IV (Low Heat Of? Hydration)
type low heat of hydration cement. This type of cement used for construction purposes, which require the amount and the increase in heat is to 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 great seriousness in which the temperature rise due the heat produced during the curing process is a critical factor. Suitable for hot climates.
5. Portland cement type V (Sulfate Resistance Cement)
Portland cement is in use requires a high sulphate resistance. Suitable for the production of concrete on land and water areas that have a high content of sulfate salts. It is suitable for the installation of the treatment plant wastewater, water, construction, bridges, tunnels, ports and nuclear plants
