The best cement for roof slab is concrete. This is a popular choice due to the fact that it lasts longer than asphalt, and because of the durability of concrete there are less leaks. However, hard hats and other protective equipment will still be needed if working on roofs.
If you are thinking about laying cement slab for your home or office, you should consider the kind of cement you will use for it. Cement is a strong and durable building material that can be used for covering almost all types of structures. One option is dry-cast polyester cement slabs. Cement slabs are available in different colors, so it’s important to choose the right one for your facility.
Cement is a low density, high strength building material. It is used to construct floors and walls, as well as in a wide variety of other applications such as concrete floor slabs, roof slabs and even roof parapets.
Cement is a fundamental part of the construction of buildings, both large and small. It is used to bring together the walls and the slab, thereby preventing any natural calamities from damaging the structure. Thus it becomes important to understand the different types of cement available for use in construction.

Cement is a powder made of limestone and clay, and it is the most common building material in the world. In fact, concrete, mortar and plaster are all types of cement. Cement can be used in many different ways during construction to hold together pieces of a structure or to make it waterproof. It is made by heating limestone and clay to very high temperatures so that they fuse together into one solid substance.
When cement hardens after being mixed with water, it forms a strong bond between two surfaces that makes them difficult to separate from each other without breaking them apart first
Here are some of the most popular types of cement that can be used for roof slabs.
Ordinary Portland Cement (OPC): This is the most common type of cement used in construction, and is also one of the oldest. It’s made from limestone, clay and silica.
High Alumina Cement (HAC): HAC has a higher percentage of aluminum oxide than ordinary OPC because it’s more resistant to high temperatures. It can be used on roofs that are exposed to extreme heat or intense sunlight, like those in desert areas.
White Cement: White / lime-pozzolanic cements have excellent resistance to moisture and alkali due to their high content of calcium hydroxide (calcium oxide mixed with water). They’re also mixed with fly ash or slag which gives them a darker color than normal white cement but still allows them to harden under low temperatures as well as ordinary OPCs
1. Ordinary Portland Cement
Portland cement is the most widely used type of cement. It is a fine powder made from limestone, clay and gypsum that is mixed with water to form a paste. The paste is then mixed with sand and stone to form concrete.
2. High Alumina Cement
Alumina cement is a type of cement that is used in the construction of concrete and mortar. Alumina cement is used in the construction of concrete and mortar for high-temperature applications. It’s used for the construction of high-temperature structures such as furnaces and kilns, which require a high degree of durability from their constituent materials to prevent damage from heat transfer.
3. White Cement
White cement is used to make concrete. It is also used in road construction, and has been for many years. White cement was originally developed in India and was used as a building material there before it became popular in Europe.
White cement is made from limestone, clay, sand and water. The exact ratios of these ingredients depend on how you want the white cement to behave when you use it: if you want it stiffer because your project requires a stronger material, then you will add more limestone; if you want your mixture softer so that it can be easily molded into shape when wet (like clay), then add more clay instead of limestone.
4. Rapid Hardening Cement
Rapid hardening cement is a type of cement that hardens quickly. It is used in construction of roof slabs and other structures. It is also used in concrete sealants and paints.
Rapid hardening cements are most commonly used as the binder phase of polymer-modified screeds where rapid curing properties are required, such as interior floor screeds or exterior driveways.
Its use has also been extended to include a range of high performance applications such as waterproofing membranes where rapid curing properties can be beneficial, typically using some combination of accelerators or chemical admixtures with the base cement.
5. Low Heat Cement
Low Heat Cement is a mixture of ordinary cement and fly ash. Fly ash is a by-product of coal combustion, which when mixed with water forms low heat cement. It is used in the construction of roof slabs, as it has excellent thermal resistance properties and gives good strength to the concrete at low temperatures. Low Heat Cement is more economical than ordinary cement as it does not require Portland Cement for its manufacture and hence there are no additional costs involved in production.
6. Air Entraining Cement
Air entrainment cement is a type of portland cement that contains air bubbles. These air bubbles help to improve the strength and durability of the concrete. Air entrainment is used for high strength concrete such as in bridges, dams and other structures that need to be long lasting.
Air entrainment occurs when water is added during mixing, as opposed to being mixed separately from the cement powder like slurry mixing does (see below). Adding water at a slow pace allows more time for air bubbles to form in the mixture; this process is known as pore filling.
7. Portland Pozzolana Cement (PPC)
- Portland Pozzolana Cement (PPC)
This is a type of cement that is made with the addition of pozzolana, which is a volcanic ash that is rich in silica. It is used for high-quality concrete products because it has excellent strength and permeability properties. However, it does not have good workability properties, so it needs to be combined with other materials like fly ash or slag.
- High Alumina Cement (HAC)
High alumina content cements are another type of refractory mortar and are usually used in the production of refractory bricks and ceramics because they have such high heat resistance qualities.
8. Portland Blast-Furnace Slag Cement (PBFS)
Portland Blast-Furnace Slag Cement (PBFS) is a type of cement that is made from blast furnace slag, which is a by-product of steel manufacturing. PBFS has a high compressive strength, which makes it suitable for constructing buildings with high rise ceilings.
Because the amounts of calcium and silicon in this cement are much lower than normal Portland cements, they have properties similar to those of fly ash cements. In addition to being used as a replacement for certain types of Portland Cement, PBFS can also be used as an admixture for other types of cement to increase their flexural strength and resistance to sulfate attack.
In this article we have covered all types of cement available for roof slab construction, with their applications and benefits so that one can make an informed choice regarding which type would suit them best based on their requirements.
- Cement for Roof Slab
- There are many types of cement available in the market. These include:
- Portland cements
- Rapid setting cements.
- Advantages and Disadvantages of Portland Cement for Roof Slab Construction:
Portland cement has been used for several decades now to provide a strong, durable and attractive finish that allows light to penetrate through the roof slab while also providing strength, durability and long lasting performance. With modern advancements in technology and chemistry, there are now many variations on this traditional construction material available to suit different needs or applications; however, it is important to consider their advantages and disadvantages before making a decision as this will ensure you get exactly what you need without any wastage or problems further down the track.
