  • Polycarboxylate-based superplasticizer compositions and methods of use
    Patent number: 10626049
    Abstract: A dispersant composition for use in gypsum and/or cementitious compositions that includes, in combination, a polycarboxylate-based superplasticizer and a synergistically effective amount of an aluminum salt. The presence of the aluminum salt, such as aluminum chlorohydrate, improves the performance of the polycarboxylate-based superplasticizer.

  • Air entrainment compositions for cement compositions
    Patent number: 5522927
    Abstract: Compositions and methods relating to cementitious compositions are provided. The use of a blend of a rosin and a tannin to entrain air into cementitious compositions is provided. A blend of a rosin and a tannin in a weight ratio of about 1:1.22 to about 1:1.86 are added to a wet cementitious composition at levels of less than 1% by weight based on the weight of the cement and air is mixed into the cement. The resulting cement will contain, e.g. 5% to 10% by volume air which improves the resistance of the set cement to freeze damage. Also provided is a method of entraining air into a cementitious composition which employs such a blend.

  • Air entrainment compositions for cement compositions
    Patent number: 5431729
    Abstract: Compositions and methods relating to cementitious compositions are provided. The use of a blend of a rosin and a tannin to entrain air into cementitious compositions is provided. A blend of a rosin and a tannin in a weight ratio of 10:1 to 1:10 are added to a wet cementitious composition at levels of less than 1% by weight based on the weight of the cement and air is mixed into the cement. The resulting cement will contain, e.g. 5% to 10% by volume air which improves the resistance of the set cement to freeze damage. Also provided is a method of entraining air into a cementitious composition which employs such a blend.
