Performance of lignite and subbituminous fly ash in

Since bituminous coal fly ash has been used in concrete to considerable advantage for several years now, it is quite likely that similar use could be made of lignite and subbituminous coal fly ashes. If so, this material could provide a plentiful supply of a potentially low cost cementing medium for use with portland cement in concrete.
