Abstract
An additive formulation for reduction or prevention of microbially induced corrosion in concrete, cementitious material (such as mortar or grout), or a combination thereof. The additive formulation comprises a Quat Silane and a fungicide, wherein the ratio of the Quat Silane to the fungicide in the formulation is in a range of about 10:1 to about 1:10, preferably in a range of about 5:1 to about 1:5.
Claims25
A method of preparing a material comprising:
- adding an additive formulation comprising a Quat Silane configured to cure on and/or within the material, a defoamer, and a fungicide to the material;
- wherein the material is in a wet-state selected from the group consisting of an uncured concrete, an uncured cementitious material, and a combination thereof;
- and wherein the addition results in a reduction or an elimination of microbially induced corrosion, wherein the defoamer is present in the additive formulation from about 2 weight % to about 25 weight %.
An article comprising:
- a material, in a wet-state, selected from the group consisting of an uncured concrete, an uncured cementitious material, and a combination thereof having an additive formulation cured therein, wherein the additive formulation comprises a Quat Silane, a fungicide, and a defoamer from about 2 weight % to about 25 weight % of the amount of the Quat Silane.
An article comprising cured concrete or cured cement having an additive formulation cured therein, wherein the additive formulation comprises a Quat Silane, a fungicide, and a defoamer from about 2 weight % to about 25 weight % of the amount of the Quat Silane.
