SYNTHEON ELEMIX is an innovative and proven concrete additive made of specially engineered polymeric spheres – lightweight synthetic particles (LSP) – that disperse uniformly throughout a concrete mix to replace a significant volume and weight of both normal and lightweight aggregate. ELEMIX evenly disperses throughout a mix to ensure uniform strength. When designing low density concrete ELEMIX can assist in the controled reduction of conrete density. Compressive strengths can be designed in the structural range to low strength concrete all depending on the particular application.
