  • Compressive Or Crushing Strength - ChestofBooks.com

    The compressive strength of concrete is very important, as it is used more often in compression than in any other way. It is rather difficult to give average values of the compressive strength of concrete, as it is dependent on so many factors.The available aggregates are so varied, and the methods of mixing and manipulation so different, that tests must be studied before any conclusions can ...

  • Compressive Or Crushing Strength. Continued -

    'The crushing strength of steel is so high that 12 or even 15 tons per square inch is perhaps a safe compressive strain. When the material is not permitted to deflect, but when in the form of a solid pillar, the strength of mild steel seems to be only 1 3/4 times that of wrought iron.

  • 95. Compressive Strength of Concrete

    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 ...

  • Elementary Principles Carpentry - ChestofBooks.com

    The theory of carpentry is founded on two distinct branches of mechanical science: one informs us how strains are transmitted through a system of framing, and is determined by that part which treats of the equality and distribution of forces; the other, how to proportion the parts, so that they may be sufficiently strong to resist the strains to which they are exposed, or that which treats of ...
