混凝土的抗压强度是按照一定规律随着龄期增长的。同时也受到温度的影响。因而它是温度和时间综合起来的十分复杂的函数。人们从长时间的实践和认识中酝酿起用另一种简单易算的温度一时间函数代替力学试验结果指示混凝土强度的设想。这种函数被称为混凝土的成熟度。由
The compressive strength of concrete increases with age according to certain rules. It is also affected by temperature. It is therefore a very complex function of temperature and time. People from the long-term practice and understanding brewing the idea of using another simple easy-to-calculate temperature-time function instead of mechanical test results to indicate the strength of concrete. This function is called the maturity of the concrete. by
