摘要
通过试验制取了大量混凝土芯样,通过分析论证提出了直径100 mm芯样非标准状态下的强度换算系数,同时还提出了直径75 mm和直径48 mm芯样非标准状态下的强度换算系数,此换算系数是在自然养护下取得,对工程实践具有指导意义。
The strength conversion coefficient of 100 millimeter diameter in non-standard state is proved through the test of concrete core sam- pies.Furthermore the strength conversion coefficient of 75 millimeter diameter and 48 millimeter diameter of concrete core samples in non-stan- dard state are obtained on the condition of the natural curing.The result has instructive significance to the project practice.
