项目摘要

Influence level of environmental factors gained from laboratory tests were investigated various factors had been taken into consideration, such as the factor concerning to the temperature, the factor concerning to the surrounding water during the freezing, and particulary, the factor concerning to the water content during the early period of freezing. These results were adopted for the estimation of temperature conditions of specimens which had been exposed to outdoors in Sapporo, and relation ship between the exposure term effect and the frost damage in freezing-and-thawing test was calculated. The effect of annually 100 freezing-and-thawing of specimens have been left and exposed to outdoors in Sapporo corresponds to the influence of 19 experimental cycles, supposing we applied to standard test (ASTM c666 A Method).
通过室内试验,考察了环境因素对冻结过程的影响程度,考虑了冻结过程中温度、周围水的影响,特别是冻结初期含水量的影响。采用这些结果对札幌室外暴露的试件的温度条件进行了估算,并计算了暴露时间效应与冻融试验中冻害的关系。假设我们应用标准试验(ASTM c666 A方法),在札幌每年100个冻融试件暴露于室外的影响相当于19个实验循环的影响。
