A molecular modified PCEtype GA was selfsynthesized, and the grindability concerning grinding duration and particle size distribution of ground cement was evaluated. Setting time, flowability, hydration heat, mechanical properties and microstructure of the ground cement were also investigated. The results show that: PCEtype GA is effective in cement grinding. With % PCEtype GA added ...
