    Abstract: PCT No. PCT/AT97/00256 Sec. 371 Date Jul. 29, 1998 Sec. 102(e) Date Jul. 29, 1998 PCT Filed Nov. 21, 1997 PCT Pub. No. WO98/23550 PCT Pub. Date Jun. 4, 1998The cement composition of this invention includes 10 to 35% by weight of portland cement, 65 to 90% by weight of a synthetic pozzolan, and an activator for reducing the positive surface potential of the synthetic pozzolan. The synthetic pozzolan is obtained by an at least partial reduction from combustion residues having a SiO2/CaO ratio of greater than 1:1 and containing Na2O and K2O as alkali oxides in an amount exceeding 1.5% by weight. The activator includes anionically active or anionic tensides.

    Abstract: The cement composition contains a) 10 - 35 wt.% cement, in particular portland cement b) 65 - 90 wt.% of a synthetic puzzolan, which was obtained by at least partial reduction of residues of combustion with a SiO2/CaO ratio > 1, like for example garbage incineration dross, and contains alkali oxide (Na2O and K2O) in quantities of over 1.5 wt.%, c) an activator for reducing the positive surface potential of the synthetic puzzolan, like for example anion-active or anionic tensides, in particular sulfonates.
