本文研究了掺Ⅲ级粉煤灰混凝土的力学性能和耐久性能,分析了这种混凝土的水化产物和孔结构,指出其性能虽不如掺Ⅱ级粉煤灰混凝土,但其某些性能却优于普通混凝土,这种混凝土适宜用于地面及水位以下的混凝土结构。
In this paper, the mechanical properties and durability of the class III fly ash concrete were studied. The hydration products and pore structure of the concrete were analyzed. It was pointed out that its performance was not as good as that of the grade II fly ash concrete, but some of its properties were excellent. For ordinary concrete, this kind of concrete is suitable for the concrete structure below the ground and water level.
