If two cubes of different sizes but prepared from the same concrete, are tested then they will show different test results. For example, strength of a cube specimen having 10 cm in size is 10% less than strength of a cube specimen having 15 cm in size.If two cubes of different shapes (such as cube & cylinder) are tested, then they will show different test rSee more on civilblogPublished: Feb 26, 2015

    Concrete strength. Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. First, though a couple of definitions may be useful: The processes of 'setting' and 'hardening' are often confused: Setting is the stiffening of the concrete after it has been placed. A concrete can be 'set' in that it is no longer fluid, but it may
