Cement can be categorized into two basic groups:
Now, let’s take a look at the natural properties that set these two types of cement apart. Along with that, we will also take a look at the sub-categories of these basic types.
Hydraulic cement – also known as Portland cement – has the ability to develop strength anywhere [whether in the air or under water]. The best thing about hydraulic cement is that it becomes insoluble in water after it has completely dried. Not to mention, it hardens even in the absence of air.
That said, hydraulic cement can be further categorized into the below-mentioned types:
Non-hydraulic cement was the basic form of cement used in the early days. Unlike hydraulic cement, it cannot harden if it comes in contact with water. Just like the name suggests, non-hydraulic cement is obtained from minerals having liquid properties such as gypsum, lime, and oxychloride. The most important types of non-hydraulic cement in Pakistan are mentioned below:
