Prospective of Glass Powder as Active Additive to Portland Cement

The usage of fine grinded silicate glass as an active additive to Portland cement has been considered in order to substitute neat cement in the cement composition, just as it is in EN 197-1 European standard by the example of active mineral additives of natural and artificial origin.

Alkaline Factor in Cements with Glass Powder

The effect of alkaline component in glass powder on the total alkaline content of cement-glass mixtures, which is limited by standards, has been investigated by means of pH-metry? Titration and different extragents. Using experimental and calculated results concerning alkaline activity of glass powder it is possible to develop chemical structure of the cement composites which would meet the standards in regard to total alkaline content.
