钢筋混凝土耐久性人工气候加速退化试验的相关性研究

钢筋混凝土耐久性退化在自然气候环境中是一个比较缓慢的过程，实验室中常用人工气侯加速退化试验方法来研究钢筋混凝土耐久性。但由于目前试验中的试验方法、试验手段、加速因素的不同，使研究成果在工程中的推广应用具有较大的局限性。为了使钢筋混凝土耐久性研究与工程实际更加紧密地结合起来，本文提出了建立标准的人工气候加速退化试验的思路，认为可以通过大量人工气候试验和自然气候试验的数据，建立一种能用于工程实际的人工气候环境和自然气候环境之间的定性关系；同时，本文也探讨了基于钢筋锈蚀的钢筋混凝土耐久性失效准则和自然气候长期试验数据的获取途径。

The relativity of accelerating deterioration between artificial weather and nature on the durability experiment of RC

The durability of reinforced concrete deteriorating in nature weather environment is a comparison slowness process,so the laboratory inside in common use atificial weather experiment to accelerate the deterioration.But there have been no agreement on the method,means and accelerating factor in the experiment at present,so it is difficult to apply the study result to the actual engineering.For making reinforced concrete durability research put together with actual engineering,the method is put forward to establish the standard artificial accelerative weather in the paper,which compare the large quantity artifical weather experiment with the data of nature weather experiment and establish a qualitative relation between the artificial weather and the nature environment.At the same time,how to obtain the data of the nature experiment and the expired standard in the reinforced concrete are also discussed in the paper.
