| 摘 要： | 优良的孔结构是现代水泥基材料高强度和高耐久性的必需条件.通过压汞法(MIP)对含有大掺量矿物掺和料的硬化水泥浆体孔结构进行了研究.结果表明,大掺量矿物掺和料的掺入使得水泥硬化浆体的早期孔隙率增加,大孔较多；随着龄期的延长,含有大掺量矿物掺和料的样品微观结构明显得到改善,孔隙率均有不同程度地降低；含有矿渣硅灰的样品90 ...

| Abstract: | The sound pore structure is necessary for the base material of modern cement with high strength and durability.Pore structure of hardened cement pastes containing large-volume mineral admixture is researched by using Mercury Intrusion Porosimetry(MIP).The results show that adding large-volume mineral admixture leads to the increase of porosity in the early stages.As the hydration age increases,the microstructure of hardened pastes containing high-volume mineral admixture is improved substantially,and all th... |

| Keywords: | hardened paste porosity aperture distribution pore structure high-volume mineral admixture |
