ARapid hardening cement
BAir entraining cement
CLow heat cement
DMasonry cement
Answer & Solution
Correct answer: C. Low heat cement
1. §1.8.2 reads: 'low heat cement is ideally suited for use in mass concrete construction such as Dams.' Because the cement releases heat very slowly, internal cracking risk in massive pours is reduced.
2. The cap is set at 65 cal/gm at 7 days and 75 cal/gm at 28 days.
