Abstract

•A micro-CT investigation of foamed cement produced in sealed mixers was conducted.•Gas bubble size of foamed cement studied generally follows the normal distribution.•The mean of the distribution increase exponentially with foam quality.•The standard deviation of the distribution increase exponentially with foam quality.•Applied pressure significantly reduces gas bubble size in foamed cement.
