What do you mean by maturity of concrete?
Well the term maturity defines itself that when the concrete achieves its state of mature condition causing the development of strength in concrete with respect to time and temperature is called the maturity of concrete.
Why do we need to know the maturity of concrete?
We mostly study about the concrete behavior and how does it achieving its strength and maturity depending on the time parameter such as knowing Initial setting time,final setting time,curing period of concrete etc. But there is also one another factor on which which the strength development in concrete can be calculated, so in order to know the strength development or to accomplish the maturity of concrete in a certain time we need to know both time and temperature.

Hence
Maturity = Σ (time x temperature), the unit of the maturity of concrete is °Ch
It is found experimentally that the hydration of concrete takes place even at -11°C lying between (-12°C and 10°C) so -11°C temperature is also considered as a Datum line for calculating Maturity.
so is a concrete sample is said to be cured at 18°C for 28 days is considered to be in a fully matured concrete then the maturity of would be equal to = 28 days x 24hrs x [18°C-(-11°C )]= 19488 °Ch
Now depending upon the strength of concrete Plowman has provided two coefficient A and B to measure
obtaining this value we can easily determine the strength achieved by the concrete at a certain temperature and a time..

Percentage of strength at maturity = A+BLog10(maturity/1000)
obtaining this value we can easily determine the strength achieved by the concrete at a certain temperature and a time..
