Cement Cemix Fastcrete 25kg bag
CEMIX® FASTCRETE® Post Hole Concrete is designed specifically for concreting in posts. It consists of a uniformly blended and proportioned mixture of sands, aggregates, Portland cement and admixtures, designed to improve the concretes performance.
The bags are simply poured gently in to a post hole containing the correct amount of water. CEMIX FASTCRETE Post Hole Concrete is designed to attain a compressive strength of 15MPa after 28 days.
• Residential fence posts
• Letter box posts
• Small sign posts
• Small clothes lines
• Non-structural decking posts
CEMIX FASTCRETE Post Hole Concrete will reach a compressive strength of 15MPa after 28 days making it suitable for non-structural work. In general, structural work requires a minimum of 17.5MPa. For all structural applications and any heavy duty post work such as sun shades or posts in high wind zones, CEMIX SUPER STRENGTH FASTCRETE Post Hole Concrete must instead be used. CEMIX SUPER STRENGTH FASTCRETE Post Hole Concrete will attain a compressive strength of 30MPa after 28 days. For applications requiring a barrow mixed concrete with workability and longer set times, use either of CEMIX MULTICRETE or CEMIX MAXCRETE which will attain 28 day compressive strengths of 28MPa and 45MPa respectively.
