Article Preview

Abstract:

The ultrafine powder composite admixture of fly ash and silica fume were researched in this article according to ultrafine powder fly ash and silica fume features.Through the different proportions of admixture strength test to determine the best ratio.The experimental results showed that appropriate admixture with 21.5%,12% of fly ash,8% of silica fume,1.5% of compound activator 28 days of flexural strength could be achieved 10.8Mpa,compressive strength could reach 54Mpa.
