Maturity Method: Estimating Concrete Strength - Maturix

The strength development of a concrete structure is strongly influenced by the temperature and weather conditions at the job site. In construction projects, knowing this strength is crucial as many further decisions depend on it. Decisions such as when to remove the forms, scheduling of post-tensioning operations, when to open bridges and roads for traffic, and determining when to remove the ...

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 ...
