| 摘 要： | 通过早期性能参数测试来快速预知混凝土的后期性能是实际工程中常见问题。研究结果表明混凝土7—56d的抗压强度发展规律符合对数函数关系，混凝土7～56d的电通量发展规律符合指数函数关系，在掌握大量试验数据的基础上，利用已建立的回归方程可以对施工中各龄期混凝土的抗压强度和渗透性进行预测。

| Abstract: | The FAQs in practical engineering are to predict the properties of concrete at later ages by using the performance parameters of concrete at early ages.The test results show that the development of compressive strength and permeability of concrete ranged from 7days to 56 days are in line with the logarithmic function and exponential function,respectively.Based on a large number of experimental data of concrete in laboratory or in site the regression equations can be used to predict the compressive strength ... |
