Moxie Shield 1800 Admixture is suitable for all forms of cementitious construction and products. Moxie Shield 1800 Admixture creates a complex chemical reaction by converting the by-products of cement hydration into a higher density cementitious material creating an impermeable substrate. The unique chemistry of Moxie Shield 1800 admixture forms an integral colloidal gel membrane prior to initial set. These colloidal gels eliminate the formation of capillary pathways and restrict the rapid evaporation of surface water. Moxie Shield 1800 increases freeze-thaw durability and becomes an integral curing compound.

- Sustainability
- Building for future generations – The Moxie Shield technology strengthens the inner structure of concrete and leads to longer lasting quality structures
- LEED Certification – Moxie Shield 1800 Admixture increases available LEED credits for projects
- Zero VOC (EPA 24 VOC) – The Moxie Shield technology is based on inorganic compounds
- Non-Toxic/Non-Hazardous – The liquid Moxie Shield 1800 Admixture is not toxic or hazardous; therefore, when protecting concrete from moisture intrusion it will not release toxic or hazardous emissions
- Water-Based – The technology is a water-based carrier for inorganic ingredients

- Dosage
Moxie Shield 1800 Admixture is used at a dosage rate of 10 fluid ounces per 94 pound sack of cement, or 11 ounces per cwt (715 mil/100 kg) of cementitious materials. Dosing rate for precast, stucco, plaster, mortar/grout, countertop and shotcrete will vary between 15 to 24 fluid ounces per 94 pound sack of cement. Include any cementitious materials such as fly ash in this calculation.
- Limitations
If the ambient temperature is below 50°F an accelerator may be needed; use moxie fastset50 to decrease the set time. Do not use chloride accelerators. In high ambient temperatures, or if a delayed set time is desired, a set retarder may be used. If additional protection from surface moisture evaporation is needed, fog misting or an evaporation retardant/finishing aid may be applied according to manufacturer instructions. Where adhered floors are to be installed do not use surface sealers/hardeners or curing compounds, as they will prevent proper mechanical bond of adhesives and increase drying time. Performs as a curing compound. In extreme conditions fog mist with water only per aci 302 concrete floor and slab construction.

Technical Details & Test Data
- Vapor Proofing
ASTM E96/ASTM E1745 Water Vapor Transmission Test and Standard Moxie Shield 1800 Admixture creates a vapor proof substrate. In ASTM E96 Standard Test Methods for Water Vapor Transmission of Materials, the tested value is more than full order of magnitude less vapor permeable than acrylic/epoxy based systems. Moxie enhanced concrete meets and exceeds the permeability value requirement of ASTM E1745 for plastic water vapor retarders.
- Water Proofing
CRD-C 48 Water Permeability of Concrete Concrete made with Moxie Shield 1800 Admixture creates a material that is impermeable to water. When tested according to CRD-C 48 Standard Test Method for Water Permeability of Concrete, there was no water transmission detectable through the sample, even when a full pressure of 200 psi was applied to the surface of the sample.
ASTM D5084 Hydraulic Conductivity Field tested samples of Moxie Shield 1800 Admixture enhanced concrete were tested as per ASTM D5084 Standard Test Methods for Measurement of Hydraulic Conductivity of Saturated Porous Materials Using a Flexible Wall Permeameter. Moxie Shield 1800 Admixture enhanced samples resisted water penetration up to 0.000000005029 centimeters per second, making it more waterproof than landfill liners and retention pond liners.
- Durability
ASTM C666 Freeze-Thaw (Method A) Independent laboratory testing using the test method A of ASTM C666 Standard Test Method for Resistance of Concrete to Rapid Freezing and Thawing was performed on a laboratory sample of Moxie Shield 1800 Admixture enhanced concrete alongside a control sample without the Moxie Shield technology. Air Entrainment admixture was not used in either sample. The control sample failed when it fell below a durability factor of 80 shortly after 300 cycles, but the Moxie Shield sample continued to 600 cycles maintaining a durability factor of 91. The test was terminated at 600 cycles.
ASTM D4060 Abrasion Resistance Surface abrasion testing was performed on samples with and without Moxie Shield 1800 Admixture as per ASTM D4060 Standard Test Method for Abrasion Resistance of Organic Coatings by the Taber Abraser. Under abrasion wheel H-22 after 1000 cycles, the Moxie sample reduced the weight loss by 30%. Under abrasion wheel CS-17 after 1000 cycles, the Moxie Shield sample reduced the weight loss by 9%. Abrasion resistance and surface hardening are significant advantages of the Moxie technology.

ASTM C39 Compressive Strength Moxie Shield 1800 Admixture adds an increased level of robustness to the concrete mix, especially when less than ideal conditions are present during the concrete placement. As per ASTM C39 Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens, compressive strength has revealed an increase compared to a control sample without Moxie Shield 1800 Admixture.
ASTM C78 Flexural Strength Along with an increase of compressive strength, an increase in flexural strength is expected as per ASTM C78 Standard Test Method for Flexural Strength of Concrete (using Simple Beam with ThirdPoint Loading).
ASTM C157 Length Change Moxie Shield 1800 Admixture enhanced concrete has shown reduced shrinkage compared to a control sample. Testing was performed in a laboratory on a typical mix design with and without Moxie Shield admixture and as per ASTM C157 Standard Test Method for Length Change of Hardened Hydraulic-Cement Mortar and Concrete.
