摘要:

研究了磷渣粉比表面积对其胶凝活性的影响，运用灰色关联理论分析了其粒径分布与活性指数的关系。结果表明：粒径30.2 μm以上的颗粒对磷渣粉的活性起削弱作用，粒径0.00~30.2 μm的颗粒对其活性起增强作用。其中，粒径5.0~10.0 μm颗粒的含量是影响磷渣粉7 d活性指数A7的关键因子，粒径10.0~20.0 μm颗粒的含量是影响28 d活性指数A28的关键因子。为提高磷渣粉的胶凝活性，其比表面积不宜低于397 m 2·kg -1，同时，应尽可能提高磷渣中粒径为5.0~30.2 μm，尤其是粒径5.0~20.0 μm的颗粒含量，并减少或限制粒径大于30.2 μm的颗粒含量。

Abstract:

The influence of specific surface area on cementitious reactivity of phosphorous slag power(PS)was studied and the grey relation degree and relation polarity between the particle size distribution characteristics and the activity coefficients of PS were investigated. The results indicated that particles could weaken the hydration activity of PS and when particle size is greater than 30.2 μm and enhance that when smaller than 30.2 μm. The volume fraction of particles with size of 5.0~10.0 μm and 10.0~20.0 μm are important determinant of the early activity index(i.e. A7)and activity index A28，respectively. Therefore，specific surface area should be greater than 397 m 2·kg -1 to improve the hydration activity of PS and it is important to increase the content of particles with size of 5.0~30.2 μm，especially with size of 5.0~20.0 μm and decreasethat of particles bigger than 30.2 μm.
