alleryStart learning →Per Table 1.5, the soundness of Ordinary Portland Cement tested by the Le Chatelier method must not exceed:
A5 mm
B50 mm
C20 mm
D10 mm
Answer & Solution
Correct answer: D. 10 mm
1. Table 1.5 in §1.9 lists Le Chatelier soundness limit as 'not exceeding 10 mm' for all OPC grades (33, 43 and 53), low heat, rapid hardening, Portland Pozzolana, Portland slag and hydrophobic Portland cements.
2. Super sulphated cement is the exception at 5 mm.
