摘要: The quantitative scanning electron microscope-backscattered (SEM-BSE) image analysis was used to evaluate capillary porosity and pore size distributions in high-strength concretes at early ages. Powers model for the hydration of cement applied interpretation results analysis. revealed that with an extremely low water/binder ratio 0.25 ages were discontinuous range finer pores. However, silica-fume-containing a had larger amounts fine pores than did without silica fume. presence fume may be responsible greater autogenous shrinkage
