 Difference Between 33, 43 and 53 Grade Cement

1. Introduction

The grade of cement refers to the compressive strength obtained by cement after the curing of 28 days.

The grade of cement that has a compressive strength of 33 N/mm² is known as 33-grade cement.

The grade of cement that has a compressive strength of 43 Mpa, 28 days after casting is known as 43-grade cement.

55-grade cement has a compressive strength of 55 N/mm² tested after curing for 28 days. 2. Difference between 33, 43 and 53-grade cement

The difference between 33, 43 and 53-grade of  cement is discussed below;

 33 Grade 43 Grade 53 Grade Its compressive strength is3 days=16 N/mm^27 days=23N/mm^228 days=33N/mm^2 Its compressive strength is3 days=22N/mm^27 days=33N/mm^228 days=43N/mm^2 Its compressive strength is3 days=33N/mm^27 days=43N/mm^228 days=53N/mm^2 Initial strength is less The initial strength is medium. Initial strength is high. The strength of 43 Grade will increase even after 28 days. The strength of 43 Grade will increase even after 28 days. The strength of cement does not increase after 38 days. Used for general construction work under normal environmental conditions. Non-structural works like flooring, plastering, etc. Used where higher strength is required like Runway RCC work, concrete bridge, etc. IS code-IS 269:1989 IS code-IS 8112:1989 IS code-IS 12269:1987
