Abstract
The invention relates to calciumaluminosilicate glasses. The glasses contain, in weight percent, 25 to 35% silica, 27 to 35% calcium oxide, 25 to 40% alumina, 0 to 4% of alkali metal oxide selected from lithium oxide, sodium oxide and potassium oxide, and 0 to 5% of titanium oxide and a total content of lithium, sodium, potassium and titanium oxides of 0.5 to 9%. The glasses, in finely divided form, react with aqueous polycarboxylic acids and set to a solid mass; cements made from the glass and polycarboxylic acids are useful in splinting compositions.
