A400 Phosphoric Acid Resistant Concrete is designed to withstand exposure to phosphoric acid and other corrosive substances in challenging environments. Its adaptable formulation makes it suitable for various concrete applications in demanding settings.

• Ideal for secondary containment, drain systems, structural concrete, and foundations in areas with phosphoric acid exposure.
• Frequently used in fertilizer plants, food processing, and animal feed industries.
• Suited for low to high slump applications in both extreme heat and cold, providing long-term durability.

Expected Characteristics:

• Working & Curing Times: Fully customizable for fast and long-lasting repairs, with optimal application temperatures up to 90°F.
• Compressive Strength: Achieves up to 9,000 psi at 28 days, based on the specific mix.
• Mixing & Application: Offers slump ranges from 1 to 10 inches and includes options for vertical overhead and low/high slump sand formulas.
• Surface Preparation: Surfaces should be clean and moist for best bonding; vibration enhances bond with CFC® or Portland surfaces.
• Finishing: No bleed water; Fusion Finish can be applied for a glass-like finish.
• Shelf Life & Storage: Standard shelf life of 6-12 months in dry storage conditions.
• Physical Properties: Wet density ranges—145 pcf (3/8” aggregate), 136 pcf (sand), and 115 pcf (vertical overhead); volume yield is 1 cubic yard or 1 cubic meter.
• Precautions: Follow critical batching procedures and protect employees from inhaling dry materials; avoid high-speed mixing to reduce air entrapment.
