A formulation including a material that is in a wet-state in which the material is an uncured concrete, an uncured cementitious material, or a combination thereof, a Quat Silane that cures on and/or within the material, a fungicide, and a defoamer.

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.

Additives for cementitious compositions are stabilized against particle agglomeration. The additive may be provided in an aqueous liquid admixture composition for cementitious compositions that includes the additive, a polymer thickener, and water, where the particles are stabilized against agglomeration and the admixture is stabilized against physical separation. The method for stabilizing the additive against particle agglomeration utilizes a pH sensitive thickener that may be activated through neutralization of acid groups on the polymer thickener. Methods of making cementitious compositions and hardened cementitious structures using the stabilized additive and admixture are also disclosed.

An additive for cementitious compositions for mitigating alkali-silica reaction (ASR) includes particles of alkali-silica reaction mitigating that are against agglomeration. The additive may be provided in an aqueous liquid admixture composition for cementitious compositions that includes the alkali-silica reaction mitigating additive, a thickening agent and water. The admixture utilizes a pH sensitive thickener in combination with pH adjustment to stabilize the particles of alkali-silica reaction mitigating additive against agglomeration. The admixture composition is used to mitigate the alkali-silica reactions in a cementitious composition. Methods of making the admixture, cementitious compositions and hardened cementitious structures are also disclosed.
