Fast-Setting Concrete Mix

Sakrete 120019 Fast Setting Concrete Mix is a pre-blended gray material designed for setting posts and poles without on-site mixing. It reaches initial set in approximately thirty minutes, eliminating the need for temporary bracing during installation. The product meets strength requirements outlined in ASTM C 387. It is intended for applications with a minimum thickness of two inches.

Sustained Load Performance

Once cured, the concrete provides structural support that exceeds the ASTM C 387 standard for strength. The fast-setting chemistry allows the material to gain load-bearing capacity rapidly, reducing downtime on the job site. It is formulated to maintain integrity under the static loads typical of post and pole installations. The mix achieves its design strength without additional blending steps by the user.

Application Constraints

This product is restricted to uses requiring at least two inches of material thickness to perform as specified. It carries a California Proposition 65 warning regarding a chemical known to cause birth defects or other reproductive harm. The mix is supplied in a pail container for direct use. It is not suitable for thin overlays or feather-edge repairs below the minimum depth.

Questions about this item

How much heat does the Sakrete 120019 mix generate while curing during an all-day project?

The fast-setting formula reaches structural strength in about thirty minutes, so the exothermic reaction is concentrated in that short window rather than sustained over a full day.

What tools or substrates must I already have on site before using this concrete mix?

You need a clean, solid base at least two inches deep, plus a water source and a mixing container; the material sets without mechanical blending.

Will the Sakrete 120019 bond reliably to an existing concrete slab that has been in place for years?

Yes, provided the old surface is sound, roughened and saturated surface-dry, the mix exceeds ASTM C 387 strength requirements for a durable bond.
