Study of a Proprietary Pozzolanic Product.

Abstract

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-536(2)) were used as a basis for concluding that silica fume was the principal constituent of this admixture (AD-644).
