The hydration activity of ternesite-dicalcium silicate composite minerals in deionized water, NaAlO2, Li2CO3 and MgSO4 was investigated. The results show that the presence of 1 mol/L [Al(OH)4]- ions in liquid significantly improves the hydration activity and accelerates the hydration of ternesite-dicalcium silicate composite minerals due to the formation of ettringite, and enhances the strength of ternesite. The strength of hydration products is 44% higher than that in deionized water. However, the presence of 0.1 mol/L Li+ ions in liquid inhibits the hydration, and the strength of hydration product is only 26% of that in deionized water. The presence of 1 mol/L Mg2+ ions in liquid improves the hydration activity of ternesite-dicalcium silicate composite minerals from 28 d to 56 d, but it inhibits the hydration activity after 56 d.
