A method for increasing the strength of concrete, including applying a coating of high-silica glaze to porcelain aggregate pieces, dispersing the glaze-coated porcelain aggregate pieces in a Portland cement matrix, bonding the high-silica glaze to the porcelain aggregate pieces, bonding the high-silica glaze to the Portland cement matrix, and curing the Portland cement matrix to yield high-strength concrete. The high-silica glaze further include silica and flux. The molar ratio of silica to flux is at least about 5 to 1 and the flux further comprises RO and R2O. The molar ratio of RO to R2O is at least about 7 to 3. RO is selected from the group including CaO, SrO, BaO, ZnO, FeO, PbO and their combinations and R2O is selected from the group including Li2O, Na2O, K2O, and their combinations.
