School of Civil Engineering，Shenyang Jianzhu University，Shenyang110168，China; aqianqian45220@126.com Keywords: Ultra-early strength; Reinforcement material; Triethanolamine; Final setting time Abstract：In the trial, the author explores sodium nitrite, triethanolamine and sodium on fluidity initial and final setting time, flexural strength and compressive strength and other properties, of early strength reinforcement material.
International Engineering Practice has proved that, according to the needs, the use of appropriate reinforcement additives will enhance and improve performance.
On the contrary, admixture improper use may appear engineering quality accident.

In the future, GHPC is bound to be a new concrete widespreadly used in civil and architectural engineering.
