Improve the Flow with Superplasticizers
When pouring IFC, having the correct slump is probably the most important factor for a successful job. A concrete mix with too high slump may cause segregation and blowouts, which can ruin the integrity of the ICF walls. However, a mix with too low slump can lead to voids and honeycombing in the walls. In a word, the slump must be perfect. When the mix is too stiff, insulated concrete form admixtures, like Supercizer 2 or Supercizer 7, are perfect for giving you that extra workability you need.
