Impact of Molecular Structure of Cement Grinding Aids on Grinding Performance
摘要
Abstract
The grinding performance of cement grinding aids is determined by molecular structure/functional group. So the influence of functional groups of grinding aids (such as the number and types of polar groups and the size of non-polar functional groups) on the performance of grinding a clinker-gypsum mixture was investigated. The results show that the organics with one polar group, diacids as well as non-polar molecules have no obvious effect on the grinding performance, however, the organics with more than two polar groups give a better grinding performance, and the grinding performance becomes superior with the increase of the number of polar groups and the structure of non-polar groups. Based on the experimental results, an adsorption dispersion model was proposed to explain the impact of molecular structure of grinding aids on the grinding performance.关键词
