E-Spec Fence Post Concrete is a high performance, early strength post hole concrete for use in setting all types of fence post and supports including wood, metal, concrete and plastic posts. E-Spec Fence Post Concrete is pre-mixed in a modern production facility which ensures a constant quality product. It contains dried sand, lime, additives, cement and ECOCEM GGBS (Ground Granulated Blast-furnace Slag). GGBS is a recycled product, manufactured from blast furnace slag, a by-product of steel making. It saves energy CO2 and other emissions and is now widely used as an environmentally friendly cost-neutral alternative to ordinary cement. ECOCEM is a European leader in the production and use of GGBS cement. Low Carbon Fence Post Concrete containing ECOCEM GGBS is a superior quality concrete.
