Cements of unique characteristics for desired performance in a given environment are being manufactured by changing the chemical composition of OPC or by adding additives or by using different raw materials. 

There are several types of cements available in the market. Each type of cement has its distinct properties. The applications of cement depend upon their unique properties which can be used in different construction and in engineering projects.

The following properties which have a huge impact on usage of cement are initial and final setting times, compressive strength, fineness and soundness.

Before starting the topic let’s have a glance on the definition of some of the important properties of any type of cement. A small note on the properties are given below:

Initial setting time

It is defined as the time taken for the cement paste to begin setting after the addition of water. In this time, the cement changes from plastic consistency to solid state.

Usually the initial setting time ranges from 30 min to several hours depending upon the type of cement.

Final setting time

It is defined as the time taken by the cement paste to fully harden and develop its full strength after it has been mixed with water.

It varies depending on various factors such as the type of cement, amount of water used and the temperature and humidity of the environment. Usually final setting time ranges from several hours to several days depending upon the type of cement.

Compressive strength

It is a measure of its ability to withstand the compressive load without breaking or cracking. The compressive strength of cement varies depending on various factors such as the type of cement, the water-cement ratio, the curing conditions, and the age of the concrete.

In general, the compressive strength of cement increases as it ages, with most of the strength gain occurring in the first 28 days after the cement has been mixed with water.

Fineness

The degree of fineness of cement is the measure of the mean size of the grains in it. It is an important property as it affects workability, strength and setting time of cement. It also helps in determining the quality and consistency of the cement. Cement which is too coarse may result in uneven setting and decrease in strength whereas cement too fine results in increased shrinkage and cracking.

Soundness

It is defined as the ability to maintain its volume and resist cracking and deformation after it has hardened.

The soundness of cement is an important property as it affects the long -term durability and strength of the structure.

Cement that exhibits excessive expansion indicates the presence of unsoundness, which can be caused by various factors such as excessive amounts of magnesia or free lime, or the presence of compounds such as gypsum.

Unsound cement leads to cracking and other structural problems in the finished structure.

In this blog, let’s discuss the properties of different types of cement and their usage.
