摘要
本文对比研究了普通硅酸盐高强混凝土、粉煤灰高强混凝土以及双掺粉煤灰和沸石粉混合料的高强混凝土的力学性能 ,研究表明 ,双掺混合材的高强混凝土的早期和后期的力学性能均较好。本文同时观测了高强混凝土的内部微观结构 ,对活性混合材的作用机理进行了初步的探讨。
? This paper evaluates the effectiveness of ternary binder blends Portland cement/Flyash/Zeolite in making high performance concrete in comparison with Portland cement controlled concrete and flyash concrete.The performance of concrete is assessed in terms of mechanical property.It is demonstrated that the concrete containing binary pozzolanic materials has high early age strength and later age strength.The paper also probed into the effecting mechanism of pozzolanic materials based on the observation of the microstructure by means of scanning electronic microscopy technique. 〔
