Abstract
A composition comprising salts of lignin sulfonate and hydroxy-aluminum and water. The composition stabilizes soil formations from the effects of water and increases the water resistance of paper products.
Claims15
A composition comprising about 30% by weight to about 95% by weight water and about 70% by weight to about 5% by weight of a solute, said solute comprising a mixture of a lignin sulfonate salt and a polymeric hydroxy-aluminum salt in a weight ratio of lignin sulfonate to hydroxy-aluminum of from about 1:4 to about 4:1.
A method of stabilizing soil surfaces apt to be rewet comprising:
- applying a soil stabilizing composition to the soil in an amount of from about 10 to about 25% by weight of the treated soil, said stabilizing composition comprising about 30% to about 95% by weight water and about 70% by weight to about 5% by weight of a solute wherein said solute comprises salts of lignin sulfonate and polymeric hydroxy-aluminum in a ratio of lignin sulfonate to hydroxy-aluminum of from about 1:4 to 4:1.
A method of stabilizing a formation penetrated by a well comprising:
- injecting a stabilizing composition down said well and into said formation, said composition comprising about 30% by weight to about 95% by weight water and about 70% by weight to 5% by weight of a solute wherein the solute comprises salts of lignin sulfonate and polymeric hydroxy-aluminum in a weight ratio of lignin sulfonate to hydroxy-aluminum of from about 1:4 to 4:1.
