Why it matters
Grade 53 gains strength fastest and is often used for structural concrete; 43 is an all-round grade; 33 is now rarely used. Higher is not always better: fast-setting cement needs careful curing in Chennai heat, and plaster and masonry do not need the highest grade.
How Elamentt handles it
The cement type and grade for each job are written in your specification; the studio estimates how many bags your plan needs.
