摘要
The issues of improved reactivity in geopolymerization reactions developed under effect of mechanical activation are examined in the fly ash obtained from the Apatity Heat and Electric Power Plant. The effect of normal and hydrothermal hardening of ash activated with sodium hydroxide solution is explored from the standpoint of changing the strength of geopolymers obtained.
