Cement

Any kind of substance that has cohesion nature and can stick materials to each other is called cement. Adhesives in building and construction industry are mainly used to stick fine and coarse aggregates and bricks together. The first cement-like material used by humans was clay and still remnants of old mud houses in desert areas can be found. Over the years different materials were performed as cement and nowadays various substances including cement mortar, gypsum mortar, polymer based adhesives, and etc. are accessible. A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

Cement Functions

Stick sand and coarse aggregates to each other

Fill the distance between sand and coarse aggregates

Makes a high-density mass

Types of Cement Used in The Construction Industry

In the construction industry, there are different types of cement. The differences between each type of cement are its properties, uses and composition materials used during the manufacturing process.
Cement is a cover material which makes a bond between aggregates and reinforcing materials. Over the years, cement in Malaysia has further developed thanks to technology.
There are different types of cement for different construction works. Keep reading to learn more about the most common ones.

Different Types of Cement

1. Ordinary Portland Cement (OPC)
Ordinary Portland Cement also known as OPC is a type of cement that is manufactured and used worldwide. It is widely used for all purposes including:
• Concrete: When OPC is mixed with aggregates and water, it makes concrete, which is widely used in the construction of buildings .
• Mortar: For joining masonry .
• Plaster: To give a perfect finish to the walls

Cement companies in Malaysia offer OPC in three different grades, namely grades 33, 43, and 53.
Besides the aforementioned purposes, Ordinary Portland cement is also used to manufacture grout, wall putty, solid concrete blocks, AAC blocks, and different types of cement.

2. Portland Pozzolana Cement (PPC)
To prepared PPC or Portland Pozzolana cement, you need to grind pozzolanic clinker with Portland cement.
PPC has a high resistance to different chemical assaults on concrete. It is widely used in construction such as:
• Marine structures
• Sewage works
• Bridges
• Piers
• Dams
• Mass concrete works

3. Rapid Hardening Cement
Cement suppliers in Malaysia also offer rapid Hardening cement. Rapid Hardening Cement is made when finely grounded C3S is displayed in OPC with higher concrete.

It is commonly used in rapid constructions like the construction pavement.
4. Extra Rapid Hardening Cement
As the name suggests, Extra rapid hardening cement gains strength quicker and it is obtained by adding calcium chloride to rapid hardening cement.
Extra rapid hardening cement is widely used in cold weather concreting, to set the cement fast. It is about 25% faster than that of rapid hardening cement by one or two days.
5. Low Heat Cement
Cement manufacturers in Malaysia offers low heat cement that is prepared by keeping the percentage of tricalcium aluminate below 6% and by increasing the proportion of C2S.
This low heat cement is used in mass concrete construction like gravity dams
