自然气候条件下混凝土内部温湿度响应规律研究
马文彬,李 果
摘 要:采用在混凝土上钻孔并埋入温湿度探头的方法测定了混凝土内部的温湿度,由此得到混凝土内部微环境下的气候条件随室外自然气候条件昼夜变化的响应曲线,并对混凝土内部微环境的温度、相对湿度滞后响应规律进行了分析。结果表明,自然气候条件下混凝土内部的温湿度响应主要表现为滞后效应,特别是混凝土内部相对湿度,不仅存在滞后效应,而且变化规律同自然气候相对湿度变化呈相反趋势。
Abstract: The interior temperature and relative humidity of concrete were measured by the embedded hygrothermal sensor in concrete, and the relationships between the exterior environmental climate conditions and interior microclimate conditions of concrete were acquired and the response curves were drawn. And then the response curves were analyzed. The results show that there is a delaying effect for the interior temperature and relative humidity of concrete to the exterior environmental temperature and relative humidity. Especially for the relative humidity in the interior of concrete, not only there is a delaying effect but also the changing laws were contrary to the changing laws of outer conditions.
