| 中文摘要 | 用环境扫描电镜和压汞测孔法观察了石灰石粉对水泥浆体和砂浆显微结构的影响。试验结果表明:石灰石粉比水泥颗粒更细,能够很好地填充水泥浆体中的孔隙,改善浆体的颗粒级配,使浆体更为密实;当砂浆含有石灰石粉时,由于石灰石粉具有填充效应,能有效地改善砂浆的孔结构,降低其孔隙率。; The influence of limestone powder on the microstructure of cement paste and sand grout was investigated by environmental scanning electron microscopy (ESEM) and mercury intrusion porosimetry (MIP) respectively. Testing results show that limestone powder is smaller than cement particles and can fill the pores and holes in the cement paste, improving the particle gradation of the cement paste, make the matrix denser. When the sand grout contains limestone powder, the limestone powder can improve the pore structure and decrease the porosity of the sand grout because of its filling effect. |
