一、粉煤灰细度对强度的影响粉煤灰的火山灰反应是在粉煤灰粒子的界面进行的,因此,粒子界面的大小直接影响到反应生成物的数量,影响到强度的大小。例如经过磨细的粉煤灰,破坏了原粒子的多孔结构,增大了比表面积,使粉煤灰活性大大增加。以甘肃西固电厂粉煤灰为 First, the fineness of fly ash on the strength of ash fly ash reaction is carried out at the fly ash particle interface, therefore, the particle size of the interface directly affects the number of reaction products, affecting the size of the intensity. For example, after pulverized fly ash, destroyed the porous structure of the original particles, increasing the specific surface area, so fly ash greatly increased activity.
