摘要
研究了弯曲荷载对硬化水泥净浆和砂浆试体碳化过程的影响。结果表明:弯曲荷载会加速水泥浆体和砂浆的碳化过程,在弯曲荷载作用下水泥浆体和砂浆的碳化动力学过程可用式x=C_0e^(aη)t^b描述,其中b值均接近1/2;碳化时间对砂浆碳化深度的影响略小于对水泥浆体的影响,而应力水平对水泥浆体和砂浆碳化的影响大致相同。
The influence of flexural load on the carbonation processes of hardened cement paste and mortar are investigated. The results indicate that flexural load will accelerate the carbonation processes of cement paste and mortar, and the dynamic processes of carbonation for cement paste and mortar under effect on flexural coad can be expressed as x=C_0e^(aη)t^b, where b equals about 1/2. The influence of time on the carbonation depth of mortar is a little less than that on the carbonation depth of paste, while the influences of stress level on the carbonation of paste and mortar are almost the same.
