| Abstract: | Adopting rapid freezing-thawing experiment approach(SD105-82),the anti-freezing property of negative temperature high performance concrete(NTHPC)is studied.Basis on the effect on anti-freezing of NTHPC in-5℃ environment by each component such as air-entraining,water-reducer,inorganic mineral,fly ash and silica fume etc,FD-1 composite admizture is manufactured and ingredient design is optimized.It is concluded that NTHPC with FD-1 possesses excellent ability of anti-freezing. |
