Cemix High Strength Fastcrete – 20kg

Cemix High Strength Fastcrete is a fast-setting bagged concrete for post hole applications needing more strength than a standard fast-set mix, reaching 30MPa compressive strength after 28 days when used to the manufacturer’s recommendations. A standard fast-set post mix suits a typical fence line, but heavier gates, structural posts, and higher-load fixings need more strength once the concrete has cured. High Strength Fastcrete is a pre-mixed blend of sands, aggregates, Portland cement, and admixtures formulated to set quickly on contact with moisture, supplied in a 20kg bag. Fencing contractors, landscapers, and builders use it for gate posts, structural post footings, and other post hole work where a stronger cured result matters more than a standard mix provides.
