粉煤灰加气砼的水化产物及其结构的研究

Study on the Hydration Products and Structure Morphology of Fly Ash Aeroconcretes

用扫描电镜研究了粉煤灰加气砼中各种水化产物的微观形态 ,对高、低温度蒸养的粉煤灰加气混凝土中水化物的种类和微观结构进行了观察分析。结果表明 :低温养护水化产物较少 ,结构疏松 ;高温蒸养水化产物较多 。

The micro-morphology of hydration products in fly ash aeroconcretes was studied by using a scanning electron microscope. The sort and microstrostrucure morphology of the hydration products in fly ash aeroconcretes seamed at higher and lower temperature were observed and analyzed. It is indicated that the products amount is less and the structure is porous for the low temperature steamed fly ash concrete, as for the high temperature steamed one the porduct amount is more and the structure is denes.
