Abstract

Abstract

In order to study the durabilities of polymer modified cement materials in road engineering, the split-strength of polymer modified cement mortar(PMCM) was studied by split test, the wearability of PMCM was studied by grinding test, the corrosion-resisting of PMCM dipping in different acidity liquors was studied, the contraction coefficient of PMCM and PMCC(polymer modified cement concrete) was studied by thermal and dry-contraction coefficient test, the frost-resisting of PMCC was studied by frost-melt cycle test, the anti-permeability of PMCC was studied by permeability test. Compared to cement materials, the split strength, wearability and corrosion-resisting of PMCM are increased, its thermal contraction coefficient is decreased, the anti-permeability, frost-resisting and dry shrinkage of PMCC are increased, its thermal contraction coefficient is decreased greatly from(-20.1) to 0.0 ℃, it is decreased little from(-20.1) to 22.8 ℃. The performances of modified cement materials are increased greatly with the increase of polymer ratio.
