粉煤灰掺量对钢纤维混凝土强度和耐久性的影响

Effect of Amounts of the Added Fly-ash on the Strength and Durability of Steel Fiber Reinforced Concrete

研究了粉煤灰掺量对C50钢纤维混凝土强度、渗透性、碳化等方面的影响。结果表明,当钢纤维用量一定时,粉煤灰用量在一定范围内增加,有利于改善钢纤维混凝土的微结构,使其后期强度和耐久性有一定提高,可配制出耐久性良好的钢纤维混凝土。

This paper studied the effect of the amount of the added fly-ash on the C50 steel fiber reinforced concrete＇s strength, permeability and carbonization. The result indicated that with the steel fiber kept unchanged in amount, Ineteasing amount of fly ash to certain extent facilitated the inprovement of steel fiber concrete＇s microstructure and thus increast its late period strength and durability;and that resulted in good quality steel fiber conrete with great durability.
