When you’re ready to purchase cement, you need to know that there are different types of cement. Each type of cement has unique properties and applications.
Most construction projects involve some form of rapid hardening cement. However, if you’re building a structure that might be exposed to extreme weather conditions or must be functional immediately, rapid hardening cement is the way to go. Let’s look at the main types of rapid hardening cement and how they compare to each other.
Types of Cement
Rapid Hardening Cement
As the name suggests, rapid hardening cement is a faster curing cement. It can cure in just a few hours and will reach its full strength in as little as a day. This makes it perfect for projects that need to be completed quickly and for structures that will bear a lot of weight or stress. Since it cures so quickly, it can also be used for repairs on roads and bridges.
Rapid hardening cement is also ideal for projects requiring high early strength, such as concrete roadways, highways, and airport runways. It is a great choice for fast-paced construction because it does not take long at all for it to set and become stable enough for use.
When it comes to building a home, a cement is the foundation of your structure. It’s what keeps everything together and is the base for your walls and other elements. What you may not know is that there are different types of cement. Cement and concrete are often used interchangeably but there are some differences between them. Concrete is made up of aggregates, water, and cement. You can use cement to create a solid foundation and other structures like driveways or sidewalks.
There are different types of cement that you should be aware of before you start a project:
Rapid Hardening Cement: This type of cement will harden very quickly, in as little as two hours! The advantage to using this type of cement is that you can finish projects quicker than with other cements. The strength of this cement is also very high and it has great resistance to chemicals, weathering, and abrasion. This type of cement is used in precast concrete products, bridges, pavements, pipes, marine structures, and mass concrete works where fast hardening is needed.
Low Heat Cement: If you’re working on projects that involve pouring large amounts of concrete at one time then consider using low heat cement instead of rapid hard

If you’ve ever taken an introductory geology course, then you probably remember learning about rocks, minerals and the rock cycle. You may even remember learning about the three types of rocks: sedimentary, metamorphic and igneous. These three types of rocks are also present in concrete: Portland cement is a type of sedimentary rock; masonry cement is metamorphic; and oil well cement is igneous. The rock that is used in concrete must be pulverized into a fine powder and can be mined from quarries or from underground mines.
We would like to take some time today to go over these three types of cement with you.
When it comes to cement, it’s not a one-size-fits-all solution. Just as there are many different types of cement out there, there are also different types of jobs that each type of cement is best suited for.
How do you know which type to choose? It’s important to remember that not all concrete is the same. Therefore, not all cement is the same either.
There are over 20 different types of portland cement used in a variety of applications. There are actually five basic types of portland cement and they can be mixed with other ingredients to produce different types of portland cement. These five basic types include:
1) Type I – Used for general construction purposes and does not contain any special properties such as sulfate resistance.
2) Type IA – Used for general construction purposes but contains air entrainment properties.
3) Type II – Used for general construction purposes but contains moderate sulfate resistance properties.
4) Type IIA – Used for general construction purposes but contains moderate sulfate and air entrainment properties.
5) Type III – Used for general construction purposes but contains high early strength properties.
Rapid Hardening Cement
Rapid hardening cement is produced by increasing the rate of cooling of clinker in its production. This cement is used in construction works where formwork is to be removed early such as road works etc. and for concrete works which require a faster strength development. The normal consistency, setting time, and strength development of this cement are similar to those of ordinary Portland cement but it develops strength much faster and attains a strength of about 15 MPa after 24 hours. It also sets more quickly than OPC and has a greater heat of hydration. As the heat generated by this cement is greater than that by other types, special precautions are required when mixing and curing concrete made with rapid hardening cement.
Rapid hardening cement is manufactured by adding a little amount of gypsum with ordinary portland cement clinker in the grinding process. It gains strength much faster than the ordinary portland cement.
Rapid hardening cement has a higher C3A content and finer grinding than ordinary portland cement. The fineness requirement of Rapid hardening cement is 450 m2/kg which is similar to that of portland pozzolana cement.
The chemical composition of rapid hardening cement is nearly same as that of ordinary portland cement. The main difference between the two cements is their fineness and gypsum content.
The rapid hardening Portland cement is a special purpose cement which sets and hardens rapidly, develops high strength and offers good resistance to sulphate attack. Rapid hardening Portland cement is suitable for precast concrete products, railway sleepers, prestressed members, marine structures, industrial floors etc. The high early strength development of this cement can also be utilised in mass concrete works where early stripping of forms and early application of load are necessary
The main characteristics of rapid hardening Portland cement are as follows:
