1. A consolidating spacer fluid for separating a drilling fluid and a cement composition in a well bore, comprising: water in an amount of about 15% to about 95% by weight of the spacer fluid;cement kiln dust;at least one additive selected from the group consisting of gypsum, bentonite, hydroxyethyl cellulose, sodium silicate, a hollow microsphere, gilsonite, perlite, a gas, an organic polymer, a biopolymer, latex, ground rubber, a surfactant, crystalline silica, amorphous silica, silica flour, fumed silica, nano-clay, salt, fiber, hydratable clay, rice husk ash, micro-fine cement, metakaolin, zeolite, shale, pumicite, Portland cement, Portland cement interground with pumice, barite, slag, lime, and any combination thereof;fly ash in an amount of about 1% to about 60% by weight of the spacer fluid; anda free water control additive in an amount of about 0.1% to about 16% by weight of the spacer fluid;wherein the consolidating spacer fluid has a zero gel time of about 4 hours or less under predetermined well bore conditions, wherein the consolidating spacer fluid is disposed in the well bore between the drilling fluid and the cement composition. 2. The consolidating spacer fluid of claim 1 wherein the cement kiln dust is present in an amount in a range of from about 1% to about 60% by weight of the consolidating spacer fluid. 3. The consolidating spacer fluid of claim 1 wherein the consolidating spacer fluid comprises dry solids used in preparation of the consolidating spacer fluid, the dry solids comprising the cement kiln dust in an amount in a range of from about 50% to 100% by weight of the dry solids. 4. The consolidating spacer fluid of claim 1 wherein the consolidating spacer fluid comprises dry solids used in preparation of the consolidating spacer fluid, the dry solids comprising the cement kiln dust in an amount in a range of from about 80% to 100% by weight of the dry solids. 5. The consolidating spacer fluid of claim 1 wherein the consolidating spacer fluid comprises at least one additive selected from the group consisting of a a lightweight additive, a foaming agent, a supplementary cementitious material, a weighting agent of any suitable size, a viscosifying agent, a fluid loss control agent, a lost circulation material, a filtration control additive, a dispersant, a defoamer, a corrosion inhibitor, a scale inhibitor, a formation conditioning agent, a water-wetting surfactant, and any combination thereof. 6. The consolidating spacer fluid of claim 1 wherein the consolidating spacer fluid comprises the slag, the pumicite, the lime, and/or the barite. 7. The consolidating spacer fluid of claim 1 wherein the consolidating spacer fluid is foamed and has a density in a range of from about 4 pounds per gallon to about 13 pounds per gallon. 8. The consolidating spacer fluid of claim 1 wherein the consolidating spacer fluid has a transition time of about 45 minutes or less under predetermined well bore conditions. 9. The consolidating spacer fluid of claim 1 wherein the consolidating spacer fluid has a transition time of about 20 minutes or less under predetermined well bore conditions. 10. A consolidating spacer fluid for separating a drilling fluid and a cement composition in a well bore, comprising: water in an amount of about 40% to about 65% by weight of the spacer fluid;fly ash in an amount of about 1% to about 10% by weight of the spacer fluid;a partially calcined kiln feed comprising SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, Na2O, and K2O; anda free water control additive in an amount of about 0.1% to about 5% by weight of the spacer fluid, wherein the free water control additive comprises at least one additive selected from the group consisting of bentonite, amorphous silica, hydroxyethyl cellulose, and any combination thereof;wherein the consolidating spacer fluid has a zero gel time of about 4 hours or less under predetermined well bore conditions, andwherein the consolidating spacer fluid is disposed in the well bore between the drilling fluid and the cement composition. 11. The consolidating spacer fluid of claim 10 wherein the partially calcined kiln feed is present in an amount in a range of from about 1% to about 60% by weight of the consolidating spacer fluid. 12. The consolidating spacer fluid of claim 10 wherein the consolidating spacer fluid comprises dry solids used in preparation of the consolidating spacer fluid, the dry solids comprising the partially calcined kiln feed in an amount in a range of from about 50% to 100% by weight of the dry solids. 13. The consolidating spacer fluid of claim 10 wherein the consolidating spacer fluid comprises dry solids used in preparation of the consolidating spacer fluid, the dry solids comprising the partially calcined kiln feed in an amount in a range of from about 80% to 100% by weight of the dry solids. 14. The consolidating spacer fluid of claim 10 wherein the consolidating spacer fluid comprises at least one additive selected from the group consisting of a a lightweight additive, a foaming agent, a supplementary cementitious material, a weighting agent of any suitable size, a viscosifying agent, a fluid loss control agent, a lost circulation material, a filtration control additive, a dispersant, a defoamer, a corrosion inhibitor, a scale inhibitor, a formation conditioning agent, a water-wetting surfactant, and any combination thereof. 15. The consolidating spacer fluid of claim 10 wherein the consolidating spacer fluid comprises slag, pumicite, lime, and/or barite. 16. The consolidating spacer fluid of claim 10 wherein the consolidating spacer fluid is foamed and has a density in a range of from about 4 pounds per gallon to about 13 pounds per gallon. 17. The consolidating spacer fluid of claim 10 wherein the consolidating spacer fluid has a transition time of about 45 minutes or less under predetermined well bore conditions. 18. The consolidating spacer fluid of claim 10 wherein the consolidating spacer fluid has a transition time of about 20 minutes or less under predetermined well bore conditions.
