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 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

Top Tips Compressive Strength v Density
The compressive strength of a block is not directly related to its dry density. Indeed, there are a wide range of options when it comes to considering which block to use. You can get 7N/mm2 blocks in aircrete medium density and dense aggregate blocks for instance. When choosing the right block type to use, it’s therefore important to
