Abstract: The low permeability of the microstructure in slag-cement paste is regarded as the major reason of the better long-term durability of these systems. However it is still not clearly understood how the refinement of the microstructure is achieved.

This study reports on the development of the microstructure in slag-cement system. Ternary systems consisting of cement blended with quartz and slag were studied. The replacement of cement was kept constant and the proportion of slag and quartz were varied to isolate the effect of slag. Our results showed that slag products form in the water space. Once the capillary porosity becomes limited, the reaction slows down.
