Q: What are the ingredients of UHM concrete?

ADepending on the formulation (i.e., high, ultra high, lightweight) UHM concrete is made from:

  • A composite binder that consists of 2 or more materials such as ground granulated blast furnace slag, fly ash, fumed silica, and metakaolin,
  • Aggregate, which may be fine sand and/or small gravel, and
  • A stoichiometrically optimized activator solution that consists of alkali-hydroxide (sodium and/or potassium hydroxide), silica, and water.
  • Proprietary retarders
  • Lightweight cellular concrete incorporates air bubble forming agents  in place of aggregate
  • Non-cellular lightweight concrete uses lightweight aggregates such as perlite.
