• Water

• Clay

• Sand

At its core, _________ is a fine, gray powder. It might not look impressive on its own, but when combined with other materials, it becomes a powerhouse of construction.

A Major stone used in the manufacturing of cement is...

• Shale

• Limestone

• Marble

• Calcium

• Silo

• Roller press

• Kiln

• Cooler

Which is NOT a major oxide in Portland Cement?

• CaCO₃

• SiO₂

• Al₂O₃

• Fe₂O₃

Which among these is the major component of Portland Cement?

• C₄AS

• C₄F

• C₂A

• C₃A

At the heart of it is a process called ________.

This cement component hydrates  and  hardens  rapidly  and  is largely  responsible for initial set and early strength.

• Tricalcium silicate

• Dicalcium silicate

• Tricalcium aluminate

• Tetracalcium Aluminoferrite

The use of this component allows lower kiln temperatures in Portland cement manufacturing, hydrates rapidly but contributes very little to strength, and also affects the colour of Cement.

• Tricalcium silicate

• Dicalcium silicate

• Tricalcium aluminate

• Tetracalcium Aluminoferrite

This component Hydrates and hardens slowly and is largely responsible for strength increases beyond one week

• Tricalcium silicate

• Dicalcium silicate

• Tricalcium aluminate

• Tetracalcium Aluminoferrite
