中文摘要:
      用静态屈服应力表征了水泥石灰石粉浆体的结构建立速率,探究了颗粒间作用力与结构建立的关系.结果表明:石灰石粉减小了水泥浆体的初始结构建立速率,且其随石灰石粉的总表面积增加而降低,随平均颗粒间距减小而增加;静电力随石灰石粉的总表面积减小与颗粒的Zeta电位增大而增大,范德华力、酸碱作用力与EDLVO作用力随石灰石粉的总表面积增加而减小;总EDLVO作用力与最大颗粒间作用力与水泥石灰石粉浆体的初始结构建立速率呈良好的正相关性.
英文摘要:
      The static yield stress was used to characterize the structural build up rate, and the relationship between interparticle forces and structural build up was investigated. The results show that the initial structural build up rate of cement decreases when the ground limestone is added, which decreases with the increase of total surface area of ground limestone and increases with the decrease of particle spacing. The smaller the total surface area is and the larger the Zeta potential of particles is, the greater the electrostatic force is. The Van Der Waals force, acid base force and EDLVO force decrease with increasing total surface area of ground limestone. The total EDLVO force and maximum interparticle force have a good positive correlation with the initial structural build up rate of cement ground limeston pastes.
