high alumina cement for structural use
Vermiculite Concrete
Vermiculite Concrete Introduction Vermiculite concrete is a low density non-structural construction product. It is insulating (both thermally and acoustically) and intrinsically fire resistant. It is normally made simply by mixing exfoliated vermiculite as the aggregate with cement and water plus additives such as plasticisers if required.

High Alumina CementGBGInnovation in Structural
In the early seventies a number of problems occurred with structural members manufactured from High Alumina Cement Concrete (HAC). High Alumina Cement undergoes a crystalline re-arrangement known as conversion which can result in a loss in strength particularly if the original water/cement ratio was not strictly controlled.
