     we polymerised the continuous styrene/divinylbenzene monomer phase of high internal phase emulsions (hipes) containing 70 vol.% cement slurry as internal phase to synthesise polymer cement hybrid materials. these novel cement containing poly(merised)hipes have an interconnected bi-phasic structure consisting of an interpenetrating network of set cement and polymer. incorporating 14 wt.% of polymer into the cement resulted in an increased compressive strain to failure as compared to pure set cement but both elastic modulus and crush strength decreased. these novel polymer cement hybrid materials have a better chemical resistance against acetic acid then pure cement and showed also no shrinkage when exposed to xylene and dodecane.
