Question

The Vitrified tile has a Water absorption of

• A. Less than \(5\%\)
• B. Less than \(10\%\)
• C. Less than \(0.5\%\)
• D. Less than \(15\%\)

Hint:

Vitrified tiles are dense and highly vitrified, so their water absorption is less than \(0.5\%\).

Answer 1

The Correct Option is C

Concept: Vitrified tiles are highly dense ceramic tiles. They are fired at high temperature so that the body becomes vitrified and develops very low porosity.

Step 1: Water absorption depends on the porosity of the ceramic body.

Step 2: If a tile has more open pores, it absorbs more water.

Step 3: Vitrified tiles have very low open porosity because a glassy phase forms during firing and fills the pores.

Step 4: Due to vitrification, the water absorption of vitrified tiles is very low.

Step 5: The standard value for vitrified tiles is generally: \[ \text{Water absorption}<0.5\% \] Therefore, the correct answer is: \[ \boxed{\text{Less than }0.5\%} \]
