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

Which is Stronger Concrete Blocks or Conventional Bricks

Apr 22, 2019 The strength of a concrete block or brick wall depends on the mortar holding the blocks together. Mortars that are rich in lime are weaker than mortars that are heavy in cement. For comparison, a lime-dense mortar can withstand around 350 psi, while a high-cement mortar can withstand 3000 psi.

Machining Aluminum Engine Blocks Engine Builder Magazine

The 6061 alloy in forged billet blocks is often pressure treated to decrease porosity and increase density. This gives 6061 billet a tensile strength of 60,000 to 70,000 psi, compared to 13,000 to 14,000 psi for A356 cast aluminum. That’s why the most demanding racing applications such as Top Fuel dragsters run 6061 billet aluminum blocks.
