FIELD: process engineering.
SUBSTANCE: invention relates to production of unsintered fly-ash gravel on the basis of acid ash. Mix for production of said gravel on the basis of acid ash of thermal electric power station contains the following elements in wt %: quicklime 5-15, anhydrite 5-15, hardening accelerator - steel-refined slag ground to smaller than 100 mcm 5-50, acid ash of thermal electric power station making the rest.
EFFECT: higher hardness without heat treatment.
