  • Method for pretreating components of a cementitious composition to control adsorption potential
    Patent number: 6706111
    Abstract: A method for pretreating a carrier component for a cementitious composition. A quantity of any component of a cementitious composition is analyzed to determine its adsorption potential in the composition. The quantity of the component is treated with an effective amount of a treatment agent to control the adsorption potential.

  • Carbon scavenger fly ash pretreatment method
    Patent number: 6599358
    Abstract: A method for pretreatment of a quantity of fly ash for use in a cementitious composition containing an air entrainment agent. An effective amount of an aromatic carboxylic acid or its salts is added to the fly ash to satiate unburned carbon in the ash. The treatment with the aromatic carboxylic acid (or hydroxy substituted aromatic carboxylic acid or its salts) does not significantly promote or retard the air entrainment functions of the air entrainment agent.
