混凝土养护质量原位检测评价方法研究进展

论述了常用的混凝土养护质量原位检测方法的原理和差异,分析了养护质量检测方法存在的问题。采用单一的检测方法难以有效评价混凝土养护质量,且评价养护质量时所需的基准值也难以准确测定,因此,可以利用混凝土渗透性与电阻变化率这个相对值之间的相关性评价混凝土养护质量;常用的检测方法主要是检测混凝土某个时间点的养护状态,无法在线连续监测养护历程,而通过监测养护历程才能更有效地评价混凝土养护质量。

Research Progress on In-situ Measurement Method for Concrete Curing Quality

The common principles and differences of the in-situ measurement methods of concrete curing quality are discussed, and the problems of measurement methods are analyzed. It is difficult to evaluate the concrete curing quality effectively and determine the reference value accurately through a single measurement method, so we should take advantage of the correlation between concrete permeability and resistance change rate to evaluate the concrete curing quality. The common in-situ measurement methods are mainly detecting the curing status of a point in time, and can not monitor the curing status of concrete continuously. In fact, effective evaluation of the concrete curing quality can be realized only by monitoring the curing status of concrete continuously.
