Strength development in concrete Understanding Cement

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
