用快速方法测定泵送混凝土强度做了大量试验研究,并通过回归分析得出了计算公式,经过重现性试验,证明该公式适用性可靠,可以用于施工中。
A large number of experimental studies have been done to determine the strength of pumped concrete by a rapid method. The calculation formula has been obtained through regression analysis. After a reproducible test, the formula is proved to be of good applicability and can be used in construction.
