【摘要】 为更真实地反映混凝土材料在自然环境下经受多种因素共同作用的耐久性能,综合分析了国内外已有混凝土耐久性研究成果,提出了模拟自然环境的混凝土综合耐久性循环试验方法,包括单一自然因素和多种自然因素耦合的耐久性循环试验。该试验方法充分利用了目前实验室常用的混凝土耐久性试验设备,具有较强的试验操作可实施性和自然环境的有效针对性,为更好地研究混凝土材料在自然环境作用下的耐久性问题提供了新的思路和试验方法。更多还原

【Abstract】 To more truly reflect the durable characteristics of concrete materials go through coupling effect of many factors under natural environment,and this paper analyzed the present research conditions of concrete durability at home and abroad.Reference to existing concrete durability test methods,and the cyclic experimental methods of comprehensive durability of concrete under simulated natural environment were developed.They contain not only the cyclic experiments of concrete durability under single natural factors,but also the cyclic experiments of concrete durability under multiple natural factors.This series of experimental methods make full use of the currently concrete durability test equipment in laboratory,and have strong practical and pertinence of natural environment.It provides a new thought and the test methods to better study the durability of concrete materials under natural environment.更多还原
