Cement – A Key Construction Material

Cement is a key building material used in any construction. Cement comes in multiple types depending on the end use application. The key types of cement are OPC and PPC. OPC stands for Ordinary Portland Cement and PPC stands for Portland Pozzolana Cement.

OPC is the most common form of cement. It is manufactured by heating limestone with a number of other elements. PPC (also known as blended cement) is made by blending 15% to 35% of the cement weight with fly ash, volcanic ash etc. to OPC cement. Both OPC and PPC cement can be used in building construction depending on the application.

One of the key characteristics of cement is the quantum of compressive strength achieved in 28 days of setting. 53 grade cement is expected to achieve 53 MPa of compressive strength in 28 days of setting. Thus, 53 grade cement is stronger than 43 grade which in turn is stronger than 33 grade cement.

The following table captures the differences between the cement types on various key attributes:

Particulars

OPC

PPC

  53 grade 43 grade  

Strength

Highest strength Lesser strength than 53 grade

Lesser than 43 grade OPC. Strength equivalent to 33 grade OPC

Speed of construction

Gains strength quickly Takes time for achieving strength Takes even longer than 43 grade to gain strength
Need for watering

Since it gains strength faster, proper watering is required to avoid cracking

Requires relatively lower maintenance such as regular watering etc.

Requires even lower maintenance than 43 grade OPC

Usage

All high load bearing elements – RCC structures like footing, column, beam and slabs

All masonry work – brick works, plaster, tiling and waterproofing

Same as OPC. PPC has better workability and gives smoother finishes because of its fly ash content

Cement price This grade carries the highest cement price 43 grade cement price is slightly lower or equal to 53 grade

PPC cement price is generally the lowest amongst all forms

 

OPC 53 grade cement is preferable for load bearing structures like foundation, columns, beams etc. PPC grade cement is more preferable for plastering and finishing work.
