Claims12
A process for the production of a storable cement-mortar dry mix, comprising the step of combining cement, aggregate, a reactive resin and a releasable hardener, characterized in that the reactive resin is premixed with an amorphous admixed material and the releasable hardener is the anhydrous reaction product of an amino group-containing hardener with an organic acid or a functional derivative thereof.
A storable cement-mortar dry mix comprising cement, from 2-25% of a reactive resin, from 2-25% of a releasable hardener, from 10-100% of fly ash, from 50-500% of aggregate, from 0-20% of cement admixtures and from 0-20% of polymer additives, all percentages (%) being by weight, based on the weight of cement, said releasable hardener being the anhydrous reaction product of an amino group-containing hardener with an organic acid or a functional derivative thereof.
