Our take on the Sikacrete 421 CI Rapid 1 Component FS Concrete 65 lb Bags Pallet of 48
Sikacrete 421 CI Rapid is a one-component, fast-setting concrete from Sika with factory-blended coarse aggregate. It gains early strength and hardens rapidly to ASTM C-928 Type R3, so repairs can reopen to traffic sooner. It is air entrained and carries a migrating corrosion inhibitor, which suits structural repairs on bridges, parking decks and industrial slabs where freeze-thaw and rebar corrosion matter. Against generic rapid-set patching mixes, the pre-blended aggregate removes field batching and the corrosion inhibitor is a step up; the trade-off is that it is a specialty repair product, not a general-purpose bagged concrete for setting posts or pouring footings.
- One-component mix with coarse aggregate already blended in
- Rapid hardening rated ASTM C-928 Type R3
- Migrating corrosion inhibitor protects embedded rebar
- Air entrained for freeze-thaw durability
- Good workability and finishing characteristics

About the Sikacrete 421 CI Rapid 1 Component FS Concrete 65 lb Bags Pallet of 48
Sikacrete 421 CI Rapid is a one-component, early strength-gaining concrete. It is a gray powder with factory-blended coarse aggregate. It is air entrained and contains a migrating corrosion inhibitor.
Because the coarse aggregate is pre-packaged, there is no field extension and no risk of reactive aggregate. The concrete is fast-setting and gains high early strength. It has excellent workability and finishing characteristics. It hardens rapidly as defined by ASTM C-928 (Type R3).
Product temperature should be 65-75 °F (18-24 °C). Ambient air and substrate temperature must be above 40 °F (4 °C).

Questions and answers
- What is Sikacrete 421 CI Rapid used for?
- It is a rapid-setting structural repair concrete for bridges, parking decks, industrial slabs and other concrete that needs early strength and corrosion protection. It is not intended for general flatwork or setting posts.
- Does it really gain strength fast?
- Yes. Sika rates it as rapid hardening under ASTM C-928 Type R3, meaning it reaches service strength quickly enough for early reopening. Plan placement and finishing around that short window.
- What does the corrosion inhibitor do?
- The migrating corrosion inhibitor works through the concrete to slow corrosion of embedded reinforcing steel. That makes it useful for repairs where rebar is exposed or chloride exposure is a concern.
- Do I need to add aggregate or other materials?
- No. The coarse aggregate is factory blended, so you add only water. This removes field batching and the risk of reactive aggregate in the mix.
- How long can I store it?
- Sika lists a 12-month shelf life. Keep bags dry and off the ground, and use them within that window.
- How much concrete does a pallet cover?
- A pallet holds 48 bags of 65 lb each. Yield depends on the placement thickness, so calculate volume from your repair dimensions before ordering.
