摘要
通过对砼进行加速老化试验 ,测定其各种物理力学指标 ,结果表明 :抗拉强度、抗渗强度、砼干容重等均与抗压强度关系很不明显 ,进一步明确了冲磨碳化等外伤与关系到的内伤的概念性区别 ;建筑物老化平价应以内部承载力。
Based on a series of accelerated aging experiments, this paper presents some new views, First of all, correlation of compressive strength and other preformance indexes of concrete is not apparent;secondly,there are conceptual differences between external damages and internal damages of hydraulic structures;lastly,aging evaluation of hydraulic structures should be based on such experimental indexes as internal bearing caplacity,impermeable strength and so on.
