Article Preview

The effect of limestone powder on immobilization of chlorine ion of Portland cement was studied by the method of the chemical analysis. The immobilization of chlorine ion of Portland cement, which was hardened by cement clinker or cement clinker and gypsum mixed limestone powder with different proportions, was tested at 28d. The results show that the amount of immobilization of chlorine ion of Portland cement increases more than doubled, and the free chlorine ion content decreases 41% without gypsum, when the limestone powder content increases from 0% to 12%; the immobilization content of chlorine ion increases first, and then decreases, the free chlorine ion content decreases a little with gypsum, when the limestone powder content increases from 0% to 8% .
