Zusammenfassung:The invention discloses a method for measuring bubble distribution in hardened concrete. The measuring method comprises the following steps: measuring the gas content and the bubble spacing coefficient of hardened concrete; the bubble spacing coefficient is calculated according to a formula (2) or a formula (3): when p/A is less than or equal to k, # imgabs1 # imgabs2 # when p/A is greater than k, # imgabs3 # wherein # imgabs4 # represents the bubble spacing coefficient, Tp represents the slurry penetrating length, N represents the number of air holes intersecting with a lead, alpha represents the specific surface area of bubbles, p represents the slurry content of hardened concrete, A represents the air content, and n represents the air content. And T alpha represents the length of the through pore. According to the measurement method, the distribution condition of the bubbles in the hardened concrete can be measured more comprehensively and accurately. 本发明公开了一种硬化混凝土中气泡分布的测量方法。该测量方法包括如下步骤:测量硬化混凝土的含气量和气泡间距系数;
