Abstract
The present invention relates to inorganic cementitious glasses, which can be in a powder form or a fibrous form. After pulverized, the glasses of the present invention are capable of replacing the Portland cement in concrete up to 65% (percentage by weight) while its strength meets the standard of the CNS61/R2001 standard. After a 28-day trial of mortar replaced by glass cement, the anti-pressure strength is 144% of which completely adopting Portland cement. The property of the glasses of the present invention is: the glass transition temperature is between 600 to 800 DEG C; the softening temperature is between 650 to 850 DEG C; thermal expansion coefficient is 6.0 to 10x10<SP>-6</SP>/DEG C. The molar percentage of the major components are: silicon dioxide (SiO2) 20 to 50%; calcium oxide (CaO) 10 to 60%; aluminum oxide (Al2O3) 0.5 to 25%; iron oxide (Fe2O3) 0.5 to 15%; the total percentage of zinc oxide (ZnO), barium oxide (BaO), Magnesium oxide (MgO), strontium oxide (SrO), tin oxide (SnO), and titanium dioxide (TiO2) is less than 15%; and the total amount of alkaline metal oxide is less than 5%. The inorganic cementitious glasses can be obtained by fusing the raw material containing the above-mentioned components. In addition, regenerated cementitious glasses (RCG) can be obtained by processing dam sludge or other wastes like glass waste or incinerator ash with refinement, pulverization, and melting procedures. The regenerated cementitious glasses have a 3 to 15% Na2O, K2O, or other mixtures.
