Rice husk ash produced under suitable burning conditions is characterized by high con tent of amorphous SiO2,high pozzolan activity and large specific surface area. 在适当条件下烧成的稻壳灰，具有无定形SiO2含量高、火山灰活性高及比表面积大等特点。
Experimental results show that the replacement of slags by pozzolan can reduce the mechanical strength Of AASC,but it can be obviously favorable for the resistance to chemical corrosion and the inhibition of the efflorescence. 实验结果表明它们能降低碱矿渣水泥的强度,但对提高抗化学侵蚀性能以及抑制泛碱有明显效果。
The microstructures of fly ash is compared with that of pozzolan in this paper. The basic characteristics of fly ash microstructure is expounded, and also the physical and chemical activity of fly ash due to its shape and microstructure. 本文比较了粉煤灰与火山灰微观结构，阐述了粉煤灰结构的基本特征以及形态与结构赋予粉煤灰物理、化学活性特征。
Blast furnace slags were partially replaced by artificial and natural pozzolanic materials, such as pozzolan , fly ash and zeolite,to produce alkali activated slag cement(AASC). 用人工和天然火山灰质材料(如火山灰、粉煤灰和沸石)替代部分高炉矿渣制造碱矿渣水泥。
