改变不同空隙率试件浸水时间及温度后测定试件吸水饱和度,研究了浸水时间、水温及空隙率对吸水饱和度的影响规律。结果表明,浸水时间对试件吸水饱和度有显著影响;水温对吸水饱和度有较大影响,相同空隙率试件吸水饱和度随着温度的升高而增加;提出了浸水饱和残留稳定度作为水稳定性判断指标。现行试验规程规定采用统一浸水时间的试验条件值得商榷,建议根据实际情况调整浸水时间以保证试件达到浸水饱和状态。
The water saturation of specimens was measured after immersion time and temperature of different porosity samples. The influence of immersion time, water temperature and porosity on water saturation was studied. The results show that the immersion time has a significant effect on the water absorption saturation of the specimen. The water temperature has a significant influence on the water absorption saturation. The water saturation of the specimen with the same porosity increases with the increase of the temperature. Judgment of water stability. The current test procedures stipulate the uniform immersion time test conditions are debatable, it is proposed to adjust the immersion time according to the actual situation to ensure that the specimen reaches the saturation state.
