Different Types Of Cement And Their Uses in Construction Industry

The infrastructural and construction industry is evolving rapidly to enhance the overall quality of life of people. Unique architectural wonders or just the way homes are built influence the standard of living and the overall safety of people. One of the key features of diverse architectural structures is their sturdiness, durability, strength, and integrity. Central to this idea is the material cement.

Cement is an essential building material that serves as a binding material to ensure your building stands the test of time with safety and durability. It is an indispensable component of construction projects worldwide. However, not all projects require the same type of cement for their development and integrity. This is why there is a wide variety of options in cement based on their specific features, capabilities, and effectiveness in diverse applications.

What is Cement?

The material serving as the backbone of the modern construction industry, cement is a powdery, fine, grey substance that helps to bind the different materials together and impact strength to the structures. The cement is created with a meticulous combination of a variety of raw materials such as chalk, clay, iron ore, limestone, shale, silica, alumina, calcium, and numerous others before heating it at high temperatures to promote the formation of a solid material called clinker. This clinker is then ground into a fine powder to create cement. This is a complex process that requires the supervision of professionals and the composition of the cement should also be considered to meet the specific quality and application requirements.

What Are The Common Types Of Cement Used in India?

There are a diverse range of options in the building materials when you plan to build a home or any other space. And so in cement. It comes in various types and grades to meet the specific requirements and needs of construction projects. You need to have a brief understanding of the different types of cement to understand which will suit your needs best. Some of the common types of cement used in the Indian construction industry include the following:

1. Ordinary Portland Cement (OPC)

The OPC cement is one of the most widely used types of cement all over the globe. This is a kind of cement that is manufactured by grinding clinker and adding a small amount of gypsum to the mixture in order to be able to regulate the setting time. There are three main popular grades of OPC cement in India including the OPC 33 Grade, OPC 43 Grade, and OPC 53 Grade. Each grade of OPC cement differs in the levels of compressive strength and is thus used in different applications. The key benefits of using OPC cement include the following:
