Know the Difference Between Cement and Concrete

Difference Between Cement and Concrete Image

Many times people fail to differentiate between cement and concrete. People normally use the word “Cement” when they mean “Concrete” in actual. They use the term cement and concrete as an alternative for each other. But in reality, cement and concrete are absolutely two different materials. Let us understand this with the help of a very common example. The relation between cement and concrete is similar to the relation between flour and a cake. Hence, one should know the basic difference between cement and concrete to overcome the misunderstanding. In this article, we have mentioned all the dissimilarities and disparities between cement and concrete. It will help you to identify and understand both the materials.

What is that Material?


Cement is a basic and core-building material used in the construction. It is a greenish-grey powder made from calcareous material like limestone or chalk and argillaceous material like clay or shale. Cement has an excellent adhesive property; hence it is used as a binding mortar. It is also used extensively in concrete and other construction works. It is thus used as one of the constituents of concrete.


Concrete is a finished or derived product made from a heterogeneous mixture of a binder, i.e. cement, chemically inert aggregates (like coarse aggregates, fine aggregates or sand, crushed stone, brick chips, etc.), admixtures and water. It is the most widely used man-made material on the earth. When water is added into the raw materials, a stone-like structure is formed as water activates the cement to get hardened.

Ingredients of the Material


  • Calcareous materials like,

01. Limestone

02. Chalk

  • Argillaceous materials like,

01. Clay

02. Shale

Ingredients of Concrete Image

Ingredients of concrete

  • Cement,
  • Aggregates

01. Coarse aggregates

02. Fine aggregates or sand,

Crushed stones or brick chips also can be used as aggregates.

  • Admixtures like Air entraining admixtures, plasticizers, retarders, accelerators,
  • Water

Above mentioned ingredients are the most basic raw ingredients for making concrete. Still, other concrete ingredients such as reinforcement, polymers, fibers, Pozzolanic materials like fly ash, GGBS, Silica fume, pigments, recycled concrete aggregates etc. are also used as they help in modifying the properties of the fresh concrete as well as the hardened concrete.

How is this Material Made?


The cement manufacturing process consists of grinding the raw material and then burning it into a kiln at around 1400 °C. The raw material thus gets converted into clinker form.

After that, the clinker is cooled and ground to a fine powder thereby adding 3% to 5% of gypsum into it. This process is either a wet process or a dry process. If you want to gain additional information about the manufacturing process of cement, then read our articles on wet process and dry process.


According to ‘A.M. Neville’[01] (Honorary Member of The American Concrete Institute), the hardened concrete is generally referred as concrete. Therefore, the process of manufacturing concrete refers to producing fresh concrete and placing it in different forms so that it can harden into structural or building material.

The following are the sequences of operations for the manufacturing of concrete.

01. Batching of Concrete

02. Mixing of Concrete

03. Transportation of Concrete

04. Placing of Concrete

05. Compaction of Concrete

06. Curing of Concrete

07. Finishing.

Production of good quality concrete requires thorough care exercised at every stage during the manufacturing process of concrete.

Above mentioned is the stepwise process of manufacturing concrete. In case you want to understand each process in detail, click on each of them to know further.



Cement is never used alone. Due to its crucial binding properties, it is used as a chief ingredient for preparing concrete, mortar, blocks, and other building materials in which it holds the other components together.

As we know, it has a unique adhesive property; hence it is used to hold together various construction materials like tiles, bricks, etc. Cement is also used as a sealant and grouting material.


Concrete is one such building material which has become an integral part of construction industry. Its unique characteristics such as strength, low-maintenance, energy-efficient, durability, and sustainability make it even more popular. It is due to these properties, concrete is used in the construction industry.

Some of the uses of concrete are mentioned below:

01. It is used in construction of structural elements like footings, foundations, slabs, columns and walls for all types of buildings.

02. Culverts and Sewers

03. Concrete Roads or Driveways

04. Marine Construction

05. Concrete Dams

06. Concrete Bridges

07.  etc.

  • Cement consists of 10 to 15% of the total mass of concrete, but the precise proportion of cement varies from mixture to mixture. It also depends upon the type of concrete being made.
  • In the ancient era, volcanic ash or tuff and lime was used as a binder in construction.
  • Portland cement is not a brand name, but it is a general term for the most common cement type. As per ‘M. S. Shetty’[02] (Author of Concrete Technology), Joseph Aspdin founded the patent for Portland cement on 21st October 1824.
  • Portland cement is a type of hydraulic cement; hence the hydration process starts after the water is added in it. The hydration process is most important for its strength gain.
  • When cement comes in contact with water, chemical reaction called hydration takes place which causes the cement to set and harden so that it holds the aggregates and other materials together in a concrete mixture.
  • Cement is an expensive building material hence; its solo usage can prove costly. Moreover, it is also prone to cracking.


  • In the fresh concrete, aggregates contribution is 60%-75%, cement is around 10%-15 %, and water is up to 15%-20%. But the exact proportion of all the ingredients varies according to the type of concrete being made.
  • In the ancient era, the Greeks and Romans were the first to use such kind of material or mortar. The material was made up of volcanic ash or tuff, lime, and sand, which acquired superior strength and better durability in both fresh as well as saltwater.
  • In the production of concrete, the water-cement ratio plays an important role as it influences the various properties of concrete like strength, workability, durability, porosity, etc. Hence, meticulous care must be taken while choosing it. If you want to know more about the w/c ratio and its effect on concrete, click the link to know more: Importance of Water-Cement Ratio in Concrete.
  • There is a myth that higher-grade concrete needs more cement. But the fact is not so. Remember, as per Indian standards, cement content not including fly ash and ground granulated blast furnace slag in excess of 450 kg/m3 should not be used unless special consideration is there.
  • Concrete can be moulded in any shape, but only when it is in plastic state. Later it gets hardened and stronger. In such state, concrete cannot be moulded. This hardening process of concrete continues for more than a year.
  • Our mentor ‘Shree Mahadev Desai‘(CMD of Sthapati Designers & Consultant PVT LTD, the leading multidisciplinary consultancy organization of India since 40 Year), shares a vast and massive work experience in this industry. He holds expertise and has attained an authoritative proficiency in the construction industry over these years. Mr. Desai advices us to avoid using hand-mixed concrete for important structural elements like columns, shear walls etc., as the use of hand-mixed concrete is very risky for such important structural elements.



Grade of Cement Image Image

Nowadays, the following three grades of cement are available in the market.

01. 33 Grade

02. 43 Grade

03. 53 Grade

However the 33 and 43 grade of cement are not available freely. The grade of cement generally differs in terms of cement strength. Because the values of 33/43/53 specify the compressive strength of cement cube in N/mm2 (Mpa) after 28 days of curing, where cement mould size is 7.06 cm*7.06 cm*7.06 cm.


The different grades of concrete are given below:

01. M5

02. M7.5

03. M10

04. M15

05. M20

06. M25

07. M30

08. M35

09. M40 etc.

Here, M denotes the mix and values like 5, 7.5, 10, 20, etc. denote the compressive strength of concrete cube after 28 days of curing in N/mm2 (Mpa).

As per the ‘Indian Standard- IS 456:2000’, grade M5 to M20 are the nominal mix concrete because its proportions are specified in the code, and those above M20, are the design mix concrete.

Read the following link to know the difference between Nominal Mix Concrete and Design Mix Concrete.



Various Types of Cement Image

15+ Types of Cement Used in Modern Construction gives you a detailed look at all the cement types mentioned above.


The application of concrete is very vast. Thus, the need arises for concrete types to meet the demand for various challenges.

An example is Ready Mix Concrete (RMC). The name itself suggests that it is a ‘ready to use’ concrete on site. Hence, it is a great option to overcome the limitation of ordinary mixtures as it reduces the work on the construction site and avoids any sort of confusion taking place. It also helps in overcoming limitation particularly with reference to quality, especially when you are dealing with unskilled labour.

The following are the different types of concrete used in the field of civil engineering.

01. Plain Cement Concrete or Ordinary Concrete

02. Reinforced Concrete

03. Lightweight Concrete

04. Ready Mix Concrete

05. Polymer Concrete

06. Pervious Concrete

07. Transparent Concrete

08. Fiber Reinforced Concrete.

09. Precast Concrete

10. Self-Compacting Concrete

11. Bio Concrete or Self-Healing Concrete

12. Green Concrete

13. Plum Concrete

14. Ferro Cement Concrete

15. Fly Ash Concrete.

16. Pre-stressed Concrete

17. High-Density Concrete

18. High-Strength Concrete

19. Air Entrained Concrete

20. Shotcrete Concrete

21. Vacuum Concrete

22. Pumped Concrete

23. Stamped Concrete

24. Limecrete

25. Roller Compacted Concrete

26. Glass Concrete

27. Pre-packed Concrete etc.


To conclude this article – Both cement and concrete are different materials. The perceived difference between concrete and cement is the case of mistaken identities. Cement is one of the components of concrete, whereas concrete is the resultant product of mix of the cement, aggregates, admixtures, and water which hardens like a rock.

Cement is in powder form, whereas concrete is a dry mix which later becomes a semi-liquid flexible material which is able to form any shape or mould and ends up finally into a stone-like hard material. The properties of cement and concrete are also altogether different. You cannot cast slab, wall, or column with cement, but you can do it with concrete. The concrete has high strength, durability, low maintenance, excellent waterproofing properties, long service life, high thermal efficiency, etc.

We hope this article proves to be of help to our readers in clearing all their doubts regarding cement and concrete, their properties, composition, types and uses.
