An environmentally friendly cement substitution material which can improve concrete performance.


Fly ash can be used with Portland cement to improve the performance and workability of the concrete.  Typical substitution rates are between 15 – 30%.  Fly ash reduces the risk of sulfate and chlorine ingress as well as help to protect against ASR from certain aggregates.  PFA and Fly Ash as an addition in concrete is covered by the specification BS EN 405-1.
