摘要
主要利用实验所得早期强度或某些参数与标准养护 2 8天强度具有一定相关关系的特性 ,应用数理统计学中的回归理论 ,建立早期强度或某些参数与标准养护 2 8天强度的关系式 ,根据要求的标准养护 2 8天强度求得应有的早期强度或某些参数值 。
There is certain correlativity between the parameters of concrete forepart strength drawn from the test and those of standard 28-day-maintenance.In this paper,the relation formula has been established by the regression theory of mathematical statistics from the formula,we can get the needed forepart strength parameters by which the mixing-ratio of concrete can be established or adjusted.
