How can I interpret compressive strength of concrete at 28 days? It is known that; many of specification stipulates that samples compressive strength of concrete must be at least "fck+delta (MPa

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
