Two blocks 6X8X9 inches, 22 months old, showed crushing strength of 2,530 and 2,610 pounds per square inch. These blocks were made of cement 1.25 parts, lime 0.5 part, sand and gravel 6 parts, and were tamped from damp mixture. It is probably safe to assume that the minimum crushing strength of well-made blocks, 1 to 5, is 1,000 pounds per square inch at 1 month and 2,000 pounds at 1 year.

2021-6-23 The 'Conditions' table indicates the minimum block strength required. That is, where a 2.9N/mm2 block is indicated, a 3.6N/mm2, 4.2N/mm2 etc block would be perfectly suitable.
