    摘要：毛细吸水作用影响玻化微珠砂浆的耐久性、保温性能和力学性能，设置正交试验，研究砂浆组分因素对毛细吸水作用的影响。试验结果表明，玻化微珠掺量是影响砂浆毛细吸水作用的主要因素，玻化微珠掺量增加，孔隙数量增多，连通性增强，形状不规则，导致毛细吸水作用增强。

    Abstract：Water absorbing driven by capillary action could affect the mortar of glazed hollow beads in durability，thermal insulation and mechanical property. The orthogonal experiment is designed to research how the different components of the mortar of glazed hollow beads influence capillary water absorbing action. According to the experiment result，the proportion of glazed hollow beads have significant effect on capillary action among all the factors in the experiment，increasing glazed hollow beads would cause more holes，stronger connection of different holes，irregularity holes，and capillary action would be enhanced by those effect.
    Key words：glazed hollow beads，capillary action，water transport
