The ARH change laws of concrete with water to binder ratio lower than 0.4 can be expressed with a non-linear equation.
水胶比小于0.4的混凝土其自身相对湿度变化规律可用非线性方程表征。

The reduction of ARH varies also with the different influences on the ratio and process of hydration of concrete with different mineral blends.
不同矿物掺合料因对混凝土水化进程与速率的影响不同，ARH下降也不同。

The next major milestone for the ARH program is the Limited User Test or LUT. This milestone will evaluate how well the ARH-70A meets the program requirements.
