| 摘 要： | 研究矿渣掺碍对于高强高性能混凝土性能的影响。水胶比为０．２８，矿渣掺量达４０％，可以配制出早期，后期强度无高于不掺矿渣，而水泥用量高达６００ｋｇ／ｍ＾３的纯水泥混凝土的相应强度，这种配合比的混凝土２８天强度在８７ＭＰａ以上；并且流动性好，可以满足泵送需要。

| Abstract: | This paper studies the effect of quatity of blast furnace slag on the strength and durability of high strength concrete and high performance concrete. When the w/e is 0.28, and the quantity of blast furnace slag is 40 percent of total binder by weight, the strength of blast-furnace-slag concrete is higher than that of pure Portland cement concrete whose cement content is up to 600kg/m~3. The strength of blast-furnace-slag concrete at 28 day is higher than 87MPa; its workability is good to suit for pumping constrction; it has low permeability and its service life is up to 75 years. The optimization quantity of blast-furnace-slag is about 40 percent at long age and 10 percent at early age. |
