3) pozzolanicity
火山灰活性
1.
There is no appropriate method or uniform standard for evaluating the pozzolanicity of CFB sulphur-fixed coal ashes,leading to difficulty in use of it as building material,because CFB sulphur-fixed coal ash has higher content of f-CaO and SO_3 than that of ordinary ash.
流化床燃煤固硫渣是一种特殊的、具有火山灰活性的燃煤副产品,由于其f-CaO和SO3含量较普通煤粉锅炉灰渣高,具有一定的自硬性和膨胀性,目前尚无统一的方法或标准准确评定其火山灰活性,影响了该燃煤副产品的建材资源化利用。
4) Pozzolanic reactivity
火山灰活性
1.
Results show that the CaO absorption capability and pozzolanic reactivity of AFA are obviously higher than that of FA.
结果表明：活化灰早期碱吸收能力和火山灰活性比原状粉煤灰显著提高。
5) pozzlizinin activity
火山灰特性
6) the activated pozzolana
活性火山灰
1.
The results showed that there were mainly three methods: one was adding the activated pozzolana to gypsum; the other was adding organic water repellents; thirdly, the two materials (the activated pozzolana and organic water repellents) were added to gypsum at some rate.
基于这一问题,文章总结了目前耐水石膏砌块处理技术的研究进展,其中采用在建筑石膏中掺入有机防水剂与活性火山灰质等材料制备耐水石膏砌块的方法具有防水效果好、强度高的优点。
补充资料：火山灰
分子式：
CAS号：
性质：火山爆发时喷出的固体火山碎屑中，直径小于2mm的浅灰至白色灰尘。系熔岩受气体爆炸作用而崩成粉，是数量最多的火山碎屑。在水泥工业上可作混合材料和制作火山灰水泥；也可用作耐火材料的原料。
