The year was 1952, and the world had no idea about high alumina cement. Lafarge was a cement producer based out of the United Kingdom. He was the man behind the birth of this variety of cement, and we can’t thank him enough, considering the many uses and beneficial properties of this cement type.

Are you currently associated with the construction business? Are you planning on monitoring what cement your workers are using for building your dream house? There could be several reasons as to why you are, but in the next five minutes, you will be dedicated to finding out what is high alumina cement and what its uses are. Keep scrolling to find out now.


What Is High Alumina Cement:

What Is High Alumina Cement

What Lafarge did was revolutionary, especially in the world of cement and tedious constructions. He started manufacturing high alumina cement by mixing grounded alumina clinkers with calcareous materials like Lime. Lafarge did not just randomly combine these materials. Instead, he used a sintering process for fusing both materials.

As compared to ordinary portland cement, alumina cement has elements like lime and bauxite, which makes the cement highly resistant to any sort of chemical attack. Also known as calcium aluminum cement, this cement variety is often used for precast concreting as well as marine constructions.


High alumina cement is easy to produce and can gain strength rapidly. Soon after its discovery, the cement gained popularity quickly, as a result. It contains the following ingredients.

  • Silica – 3 to 8%
  • Alumina – 37 to 41%
  • Lime – 36 to 40%
  • Iron Oxide – 9 to 10%
  • Titanium – 1.5 to 2%
  • Magnesium – 1%
  • Insoluble Resides – 1%


High Alumina Cement Properties

While going through the high alumina cement pdf, we came across all the properties of this cement variety. Thus, the properties of this type of cement are as follows,

  1. Calcium Aluminium cement has high resistant properties when it comes to chemical attacks.

  1. Moreover, Calcium Aluminium cement has a low level of pH, while the refractive index of the same is pretty high.

  1. High Alumina cement hardens very quickly with properties of high durability in the case of sulphuric acid.

  1. When this cement variety is added to refractory castables, a ceramic bond is formed at a high temperature.

  1. Moreover, it resists chemical corrosion since it’s used for constructions purposes in building water pipes, factory chimneys, drains, and coastal structures.


The uses of high alumina cement are the primary reason behind its popularity since its discovery in 1952. Thus, the uses of this cement variety are as follows,

  • It is popularly used in conducting marine constructions as well as for the construction of sewer infrastructure. This is because the cement has rapid hardening properties as well as it gains strength quickly.
  • This cement variety is also commonly used in construction work involving refractory concretes. This is because, in such situations of high temperatures, more strength is needed.

Is High Alumina Cement Good To Use?

Is High Alumina Cement Good

Are you wondering whether high alumina cement is good enough for use? My solution to this dilemma would be to understand the advantages and disadvantages of this cement variety before actually making any decision. Thus, scroll down and go through the advantages and disadvantages of this cement.

Advantages Of High Alumina Cement:

The advantages of this type of cement are as follows,

  1. Since this cement variety has a high setting time compared to other varieties, it takes more time for both mixing and placing.

  1. Another great advantage of chemical aluminum cement is that it can withstand conditions of high temperature. In this context, another benefit is the cement also has a high resistance to fire.

  1. Since it has a compressive strength that is very high, it is extremely reactive with heavy resistance to chemical actions.
  2. Since the evolved heat is heavy during the setting of the cement, the frost action is pretty low.

Disadvantages Of High Alumina Cement:

The disadvantages of this type of cement are as follows,

  1. Since the required amount of heat for manufacturing chemical aluminum cement is relatively more, the production cost of this cement variety is pretty high.

  1. Since the amount of heat evolving during the setting time of chemical aluminum cement is pretty high, this variety cannot be simply utilized for any work related to mass concreting.

  1. The fineness of alumina cement is kept at 2250 cm square/gram or a little more than that. The fineness is so much that it’s best not to be brought in contact with the human eye or mouth!

Frequently Asked Questions (FAQs):

1. What Are The Advantages Of High Alumina Cement?

It can withstand very high-temperature conditions. In places where the weather is cold, the action of the frost is reduced due to more amount of heat evolution during the setting period.

2. What Is The Problem With High Alumina Cement?

Construction structures made from chemical aluminum cement do undergo several changes within their crystalline structures. In the construction world, this event marks transformation or conversion, and it happens to cause a loss in strength, which either warmth or moisture has generated.

3. Why Is High Alumina Cement Content Banned?

Although the chemical aluminum cement has several benefits, many countries have banned using this cement for construction purposes after several high-profile failures.

Wrapping Up:

When Lafarge discovered high alumina cement in 1952, the benefits of the cement stumped most industry experts. Then, for the first time, building material was found that could not just resist high temperatures but also withstand fire. In the 1950s, this characteristic appealed to the masses because people were just finding out that you can protect your house from fire and similar issues via building materials with the properties of ordinary restaurants.

Although this cement was the result of a complete man-made chemical reaction, people were still pretty shocked. Even after a few high-level failures, this cement has been banned in several countries, yet it continues to be used in places where it has not been banned. Thus, if you live in one of those countries, it’s time you check this cement out and use it for your next big construction project.
