Various curing condition and different amount of water evaporated in early-age curing would lead to different strength of concrete.
早期养护条件不同，混凝土失水量不同，则混凝土中后期强度也不相同。
For the concrete which losing water is little at early-age, strengthen curing, the strength of concrete will be compensated.
对早期失水较少的混凝土，加强湿养护，混凝土强度能得到较大的补偿。
The accuracy of the curve is tested and verified by the practical engineering, and the curve can be used as the curve for early-age ground slag concrete strength by rebound method in Zhengzhou.
经工程实践验证了该曲线的测试精度，建议可作为郑州市早龄期磨细矿渣混凝土回弹法的专用测强曲线。
