**What Is 53 Grade Cement**?

**The Grade** assigned to cement indicates the **rolling resistance of cement. **The strength gained by concrete usually compressive strength is measured after 2**8 days **after curing.

**Curing **should be carried out in a very adequate manner to ensure the required **strength of concrete. **Curing controls the** rate of hydration** of the cement, which is necessary to obtain adequate **compressive strength **of the cement.

Very commonly used cement in construction is **OPC **(Ordinary Portland Cement) which has 3 grades **33, 43, **and **53.** As per **The Bureau of Indian Standard,** this grade indicates compressive strengths of cement and is expressed in Mega Pascal **(Mpa), i.e. N/mm2.**

**Compressive Strength** of cement or concrete after hardening obtained is proportional to **load per unit area. **The **load **has the unit **Newton (N) **and the area is calculated in **mm2. **The differences in grades **33, 43, and 53** grades cement are discussed below,

**Grade-33 Cement.****Grade-43 Cement.****Grade-53 Cement.**

**Grade 33 Cement**

**Grade 33 OPC (Ordinary Portland Cement)** is very rarely used nowadays for the construction of buildings.** Higher Strength Cement **is becoming popular nowadays because of its **strength-providing capability.**

However, **OPC 33 **can be suitable for **general uses **such as paving, mass concreting, and plain cement concreting. Also, the **workability **of **Grade 33 Portland cement **is higher as compared to other grades of cement.

It could also be used in plaster and **masonry mortars. The fineness** of Grade 33 cement is** 300 kg/m2**.

**Crushing Strength** of Grade 33 Cement at interval of 3, 7, and 28 days is listed below,

**3 days- 16 N/mm2****7 days- 22 N/mm2****28 days- 33 N/mm2**

**Grade 43 Cement**

In many constructions works, Grade 33 is replaced by **Grade 43 of cement,** because of its higher **strength **and **durability**.

**OPC **possesses medium properties as compared to **Grade 33** and **Grade 43**. Such as Grade 43 is **cheaper **than Grade 53 but is costly than Grade 33. Similarly, the **workability **of Grade is greater than **Grade 55 **cement but is lesser when compared to Grade 33.

**Grade 43 cement** is suitable in the construction of **reinforced concrete **(also called **R.C.C**), RMC (also called Pre Mixed Concrete or **Ready Mix Concrete**), and **Pre Cast Concrete** for Construction purposes.

**Fineness value **for Grade 43 OPC cement is **225 kg/m2.** Grade 43 cement holds an excellent ability to resist** sulfate attack** and is made to have a low **chloride content.** Whereas, **crushing resistance **offered by the same is listed below,

**3 days- 23 N/mm2****7 days- 33 N/mm2****28 days- 43 N/mm2**

**Grade 53 Cement**

**53 Grade Cement (OPC)** is widely used when comes to Construction Industry for **projects **that require high tensile strength. The strength gained by **Grade 53 Cement **is quite earlier than Grade 33 and grade 43.

**The heat of Hydration** of it is high, but it is further supported with **magnesium strength** which is **6.01% **in **OPC 53 **which in turn finally affects compressive strength**.**

**Grade 53 cement** has a good ability to **resist sulfate** and requires a small amount of cement because of its **high strength **as compared to other grades of Portland cement.

Grade 53 cement uses in construction,

- In the construction of
**Huge Structures**such as**Bridges**. **Precast Components**of Structure**Factories, Buildings, Complexes**- Construction of
**Concrete Sleeper**to sustain the large load

**Crushing Resistance** values of** grade 53 cement** at an interval of 3, 7, and 28 days is listed below,

**3 days = 27 N/mm2****7 days = 37 N/mm2****28 days = 53 N/mm2**

## 1. **IS Codes For 53 Grades Of Cement**

- For Grade 33 Cement
**IS 269**is recommended - Grade 43 Cement follows
**IS 8112**for construction - For 53 grade
**IS 12269**is recommended

## 2. **Compressive Strength**

Compressive Strength is calculated using following procedure,

**Water is added**to the cement along with**sand**in proportion.- After
**proper mixing**is ensured to obtain uniform concrete. - Which is later poured in
**formwork**and**cured**till hardening. **Cubes obtained**are tested in the**laboratory at 27 ° C**after 3 days, 7, and 28 days of intervals.**Testing**shows the strength obtained by cement in that time interval.

## 3. **Initial Strength**

It can be noticed that the** Initial Strength** of **53 Grade Cement **is greater than **33 Grade** and **43 Grade** of Cement. Initial quick strength gain does not allow Grade 53 cement to** increase strength** further after **28 days**.

However, **Grade 53 **and **43** continues to** gain strength** after **28 days **because of slow strength gain characteristics. Over the period of time Grade 33 cement and 43 grades, cement has the ability to achieve the same **maximum strength** as that of 53-grade cement.

**4. Heat Of Hydration**

At the time of** initial setup,** Grade 53 Cement releases heat during the curing period known as the** heat of hydration** at a much faster rate as compared to the heat liberated by **33 and 43-grade cement.**

This increases the chances of **microcracks** in **Grade 53 Cement,** which may not be visible on the concrete surface. To counter **strength problems**, site **supervisors **suggest increasing the amount of cement in the mix. But this might lead to the problem of micro-cracks in the **concrete**.

Therefore, the **Cement of Grade 53** should only be used only at such circumstances where quick** strength gain **of concrete is required.

**5. Price Comparison**

The price of 33 Grade Cement is the **lowest **of all that is **lesser **than 43 Grade Cement and 53 Grade. The price of 43 Grade Cement is **comparatively higher** than Grade 33 but **lesser **when compared to Grade 53 of Cement.

The price of **Grade 53 **Cement is the **highest **of all because of its outstanding and reliable characteristics.

**6. Uses**

As mentioned earlier **Grade 33 Cement** is used **rarely nowadays**, because of the availability of higher strength cement with **considerable cost.** Grade 33 Cement can be used in manufacturing **low strength concrete** i.e. below **M20 concrete**.

The cement of **Grade 43** is used in **PCC and RCC** works, preferably where the concrete of grade **M30 is required.** For the works such as plastering, tiles, masonry and stone masonry, **flooring**, etc, the** **use of **43 Grade cement** is recommended.

Similarly, **Grade 43 Cement** is recommended for **finishing **all types of buildings, bridges, culverts, roads, water retention structures, etc.

OPC i.e. **Ordinary Portland Grade** 53 Cement is used in all types of **RCC Structures** which include various components of structure such as footing, columns, beams, and slabs, where **initial and final strength requirement** is the main structural necessity.

A concrete grade of **M30 **and above are well suited for such **cement grade**.

**Building – Activity,**

- Tiles, Building Blocks, Sleepers, Pipes, Paving Blocks, etc
**precast concrete materials**. - For the works involving
**prestressed concrete**, such are Flyover, Silos, and Bridges. - Other c
**onstruction structures**such as Railway Tracks, Concrete Roads, Bridges. - Concreting process for
**cold-weather**regions, cement grouting, and instant clogging.

**Each grade of cement** mentioned above is suitable for a different **set of tasks **because of its **differential properties.** Each of them is having a variable level of resistance offered to the **loading**. Hence care should be taken while selecting each one of them for a specific purpose.

It is well suggested by the **standards **that the use of incorrect **resistance levels **for a job by selecting the specific grade of cement can affect your overall **structural design**.
