Studies of Macro Defect Free Cement Based Composites with Cation Compounds Li Beixing Zhou MingkaiEffect of cations added into HAC/PVA based MDF composites on cross linking reaction of polymer and hydration degree of cement were investigated by hydration heat analysis, FT IR and quantitative XRD. The results show that the characteristics of polymer gels cross linked with cations have a great bear on processing and mechanical behavior of MDF composites.MDF cement; foreign cation;\ processing;\ mechanical property
