Which brick undergoes maximum shrinkage on drying ?
Correct answer: B. Fireclay bricks
- A. Tar bonded dolomite bricks
- B. Fireclay bricks
- C. Magnesite bricks
- D. Chromite bricks
Explanation
Fireclay contains a relatively high proportion of plastic clay, which loses water and contracts substantially during drying. The fired aggregate in magnesite, chromite, and tar-bonded dolomite bricks generally undergoes less drying shrinkage.
