Simply put, maturity is a real-time approach to estimating the compressive strength of in-place concrete, and relating it to the effects of temperature and time.
This process is used to measure the progression of the curing process; it is an accurate indexing method of figuring out the strength of the concrete, while it cures.
The maturity method, often just called maturity, carries out strength testing in a non-destructive manner, making it ideal for use by builders, suppliers, and subcontractors. It is the perfect way of conducting quick evaluations to determine the exact instant at which the concrete reaches its required strength.
Since maturity is directly related to the strength and durability of the concrete, this method is the best way to measure it without depending on standard laboratory testing, or using test specimens. It can virtually eliminate the use of concrete cylinder break testing, with the exception of breaking cylinders as a means of verification.Read post
