Concrete blocks are often made of 1:3:6 concrete with a maximum size aggregate of 10mm or a cementsand mixture with a ratio of 1:7, 1:8 or 1:9. These mixtures, if properly cured, give concrete blocks a compression strength well above what is required in a onestorey building. The blocks may be solid, cellular or hollow.

the compressive strength of concrete. Otherwise, the compressive strength of concrete is defined as the maximum crushing stress endured by the concrete. Purpose of this Test. Assume a slab at our site is designed to cast M25 grade of concrete, but we could not define its strength in the semisolid state.

Oct 28, 2013 · The American Concrete Institute recognizes 28 days or "the test age designated for determination of the specified compressive strength."5 Therefore, when a specifier calls for 5,000 psi concrete at 28 days, this tells the concrete producer to select a mix design that will attain a minimum of 5,000 psi 28 days after manufacture.
