The improvement of the activation treatment on the activity of high-magnesium nickel slag was investigated by introducing MgO in high-magnesium nickel slag and remelting it with water quenching，and the engineering performance and hydration products of activated high-magnesium nickel slag as cementitious material were studied using water glass as the activator.The results showed that the compressive strength of high-magnesium nickel slag based geopolymer after activation treatment could reach 35.60 MPa，which was 60.7% higher than that of untreated high-magnesium nickel slag-based geopolymer.The factors affecting the compressive strength of geopolymers in order of predominance were water glass dosing，m（high-magnesium nickel slag）∶m（fly ash），and water glass modulus.The main hydration products were sodium-magnesium-aluminum silicate gel（N-M-A-S-H），and a small portion of aluminosilicate and hydrated calcium silicate，etc，without Mg（OH）2.A large number of gelling phases such as N-M-A-S-H wrapped around unreacted FA，etc.to form a dense gel-crystal phase structure.This study provided some guidance for the practical application of high-magnesium nickel slag as raw material for the preparation of geopolymers，and provided a new idea for improving the pozzolanic activity of slag.
Key words： high-magnesium nickel slag; activation treatment; geopolymer; N-M-A-S-H; fly ash
