The invention designs a high-strength cement additive to solve the problem that in the prior art, the use amount of cement clinker is large. The high-strength cement additive is prepared from, by mass, 30-40% of calcium oxide, 25-30% of alunite, 5-10% of magnesium oxide, 1-3% of sodium tripolyphosphate, 1-3% of sodium sulfite, 15-25% of mirabilite, 5-10% of potassium formate and 1-3% of triisopropanolamine. The use amount of the cement clinker can be reduced to 30% by using the high-strength cement additive.
