早期推定混凝土强度方法是很有实际应用价值的。我们单位从八二年十一月开始应用以来已两年多了,取得了一定的经济效益和社会效益。为了获得更好的效果,有必要逐步提高早期推定的精度,这就需要在实际使用过程中不断地修正早期推定混凝土强度的关系式。早期推定混凝土强度的关系式原先是由试验室按部颁标准经过30对组的试验建立的。在使用过程中,随着时间的推移,我们可以逐步获得大量的取自实际生产的数据。这些数据与原先试验室的数据不同,
The method of early estimation of concrete strength is of practical value. It has been more than two years since our unit began to be used in November of 1982 and has achieved certain economic and social benefits. In order to obtain better results, it is necessary to gradually improve the accuracy of the early estimation, which requires constantly correcting the relationship of the early estimated concrete strength during actual use. The relationship between early presumption of concrete strength was originally established by the laboratory in accordance with the ministerial standards of 30 pairs of tests. In the course of use, over time, we can gradually obtain a large amount of data from actual production. These data are different from the original laboratory data.
