The recent researches and problems about liquid accelerated agent in China are discussed.

It is found that partial hydrolysis polyacrylamide, triethanolamine and potassium dichromate all can form an even and stable solution with the liquid sodium aluminate, and the synergistic ingredients can obviously enhance the effect of the liquid accelerated agent.

When mixing amount superfluous,lots of hexagonal aluminate hydrates and monosulfate were formed and calcium silicate hydrate gel and columnar crystal ettringite were less,causing imperfect structure,the effect of the liquid accelerated agent was reduced.
