Eirtek Minerals Ltd supply Pulverised Fuel Ash (PFA). This material is excavated and then screened prior to dispatch.

Our Fly Ash meets the requirements of BS 13055 for Lightweight Aggregates.

 

Conditioned fly ash can be used as a general or structural fill material, for highway construction, or for capping. It can also be used as an addition in concrete, as an aggregate/filler in cementitious grouts, or bituminous road materials and in cement manufacture. Conditioned fly ash is low density so can be used as a fill material over weak ground. When used in grout it gives good yields. There is very little consolidation after placing and the material offers immediate strength from the high value of apparent cohesion an a high angle of shearing resistance, while the continuing reaction between PFA and free lime means that it offers strength gains with time.

Conditioned ash is self-supporting, minimising the need for shoring. It has low permeability, assisting water run-off and it is a stable material chemically and physically. The spherical shape of the ash particles provides the additional benefits of a reduced water to solids ration, reduced bleeding and good flow properties.
