Which of the following additives/water proofing agents is added to lower the hydrophilic (moisture loving) characteristic of cement ?
Correct answer: B. Calcium & aluminium stearate
- A. Xanthates
- B. Calcium & aluminium stearate
- C. Stearic acid
- D. Formic acid
Explanation
Calcium and aluminium stearates form water-repellent coatings within cement pores, reducing the cement's hydrophilic character. Xanthates and formic acid do not serve this usual waterproofing function.
