The relationship between autogenous shrinkage and pore structure of cement paste with mineral admixtures
AbstractIn this paper, the combination of fly ash and silica fume, or fly ash and blast furnace slag were used as the composite mineral admixtures in cement paste. The autogenous shrinkage and the pore structure of the hardened cement paste with mineral admixtures were tested, and the relationship of the autogenous shrinkage and pore structure also was discussed. The results indicate that fly ash can reduce the autogenous shrinkage, and silica fume can increase the autogenous shrinkage, and the effect of blast furnace slag is between the two above; although both silica fume and blast furnace slag can weaken the porosity and the mean diameter of cement paste, and increase the volumetric percentage of pores whose diameter is between 5 and 50nm and pore specific surface, silica fume is better than blast furnace slag in changing the pore structure. The relationship between the autogenous shrinkage and volumetric percentage of pores whose diameter is between 5 and 50nm is obviously proportional.
