摘要
采用直线导线法和面积比法两种方法测量硬化混凝土气孔系统参数,包括含气量、气泡比表面积、气泡间距系数、孔隙率、浆气比等,通过对比两种方法的测量结果,分析影响测试结果的因素和两种测试方法各自的优缺点,为硬化后的混凝土气孔系统参数测量和检测的准确性和可靠性提高提供参考。
The parameters of hardened concrete air-voidsystem were measured by linear traverse method and area ratio method,including air content,bubble specific surface area,bubble spacing coefficient,porosity,slurry air ratio,etc.By comparing the measurement results of the two methods,the factors affecting the testing results and the advantages and disadvantages of the two methods were analyzed,which provided a reference for improving the accuracy and reliability of the measurement and detection of hardened concrete air-void system parameters.
