Polyheed 819 

Polyheed 819 is a multi component, non-chloride, mid range water reducing admixture designed to improve the performance of concrete both in the plastic and hardened states.  Polyheed 819 is a versatile admixture able to produce mid range slumps without retardation.  Its formulation contains materials able to improve the concrete’s workability and finishability. Polyheed 819 meets and exceeds the requirements of AS1478 Type MWR.

Polyheed 819 is recommended for:

• all types of concrete where a non-chloride water reducing admixture is required, especially in the mid range slump band (100-150mm)
• improving the performance of pumped concrete, shotcrete and conventionally placed concrete
• improving the performance of plain, reinforced, precast, light weight or standard weight concrete
• use in white or coloured concrete
• use in architectural concrete, especially where off-form and/or surface finish is critical
• use in concrete containing harsh aggregates and/or manufactured sands
