| Abstract: | An unstable water-soluble complex compound can be formed by the reaction between active ion of permeable crystalline coating and calcium ion,a great quantity of needle water-fast crystals are produced by complexation-substitution reaction,which can prevent the pores and cracks of concrete and improve the impermeability of concrete.In this paper,the stability constant of unstable complex compound is measured by spectrophotometry. |
