Compression Machines. Humboldt's concrete compression frames are designed to handle the daily demands of testing concrete cylinders, beams, blocks and cubes. Humboldt's compression machines span a testing range from 30,000 to 500,000 lbs. (1112 to 2,224kN)....

Properties of Concrete Blocks — Strength

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 parts, lime part, sand and gravel 6 parts, and were tamped from damp mixture. It is probably safe to assume that the minimum crushing strength of wellmade blocks, 1 to 5, is 1,000 pounds per square inch at 1 month and 2,000 pounds at 1 year....
