Abstract:
1. A solidification matrix consisting essentially of: (a) a polycarboxylic acid polymer selected from the group consisting of: a polyacrylic acid polymer having a molecular weight of between about 1,000 and about 100,000, a modified polyacrylic acid polymer having a molecular weight of between about 1,000 and about 100,000, and a polymaleic acid polymer having a molecular weight of between about 500 and about 5,000; (b) sodium carbonate; and (c) water; (d) wherein the solidification matrix is a hydrate solid; (e) wherein if heated at a temperature of 120 degrees Fahrenheit, the solidification matrix is dimensionally stable and has a growth exponent of less than 2%; and (f) wherein the solidification matrix is phosphorus-free.
