Petrographic examination and limited chemical analysis were used to identify constituents in a proprietary anti-corrosion admixture AD-644 for concrete. Petrographic examination included X-ray diffraction, light microscopy, and scanning electron microscopy. The CaO content of the sample was determined by chemical analysis as a basis for estimating cement content of the sample. The results indicated that the admixture was largely silica fume containing about 12 percent portland cement and a small amount of organic material which was believed to be a water-reducing admixture. Properties of a known silica fume AD-5362 were used as a basis for concluding that silica fume was the principal constituent of this admixture AD-644.
