Comparison of inorganic binders porosity measuring methods
Original language description
There are various methods for determining porosity of inorganic binders, but they differ mainly in the extent ofdetermining pore size and connectivity. In this work, a set of samples containing varying content of cement andhydraulic clinker-free binder prepared from FBC ash was prepared. After that, the measurement of porositywas performed using several different methods, among which belong image analysis, mercury intrusionporosimetry and air pressure method, i.e., determination of the size of air pores in fresh unhardened binder.The choice of the method led to different porosity results, which were assessed. It was therefore possible toobserve how the results are affected by the measurement ranges of the individual methods. Furthermore, thedependence of the porosity on the water to binder ratio was evaluated.
