A granular composition, comprising:
- at least 50 wt. % of an aluminosilicate ash base material;
- and
- about 0.001 wt % to about 5 wt % of a leach reduction additive, wherein the leach reduction additive comprises one or more of a liquid alkane, a paraffin wax, a fatty acid ester, stearic acid, oleic acid, palmitic acid, a glyceryl fatty acid ester, an alkene, a cycloalkane, methyl cellulose, a silicone, and a trihydroxy alcohol ester of one or more of stearic acid, oleic acid and palmitic acid.
A granular composition, comprising:
- at least 50 wt. % of an aluminosilicate ash base material;
- about 0.001 wt % to about 5 wt % of a leach reduction additive, wherein the leach reduction additive comprises one or more of a liquid alkane, a paraffin wax, a fatty acid ester, stearic acid, oleic acid, palmitic acid, a glyceryl fatty acid ester, an alkene, a cycloalkane, methyl cellulose, a silicone, and a trihydroxy alcohol ester of one or more of stearic acid, oleic acid and palmitic acid;
- and
- about 0.1 to about 20 wt. % of a binder.
