硅酸盐通报

本文通过电泳法系统测定了水泥浆体体系的ζ-电位,研究了实际工程应用中,对水泥浆体性质影响较大、实际可控的五个因素对水泥浆体ζ-电位的影响规律.研究证明:水化时间,掺合料对水泥浆体的ζ-电位影响不大;低水灰比时,水泥浆体中电解质离子浓度较高;聚羧酸减水剂能有效提高水泥颗粒表面ζ-电位,但聚羧酸减水剂对...

材料科学技术(英文)

Several factors affecting the ζ-potential of nanodiamonds were studied. The Chemical Mechanical Modification (CMM) of surface, different surfactants and its dosage, and inorganic ions on the ζ-potential of nanodiamond sample L were studied using ZETASIZER3000HS and Nexus470. Results show that the ζ-...
