摘　　要：利用聚合物水泥包覆膨胀珍珠岩制成改性珠粒,并将改性珠粒掺加到水泥砂浆中制成保温砌块。测试了改性珠粒的吸水率、筒压强度及导热系数,并据此确定了聚灰比;研究了改性珠粒不同掺加比例的保温砌块的密度、导热系数、吸水率以及强度的变化,并对掺加比例与导热系数进行了线性回归分析。Expanded perlite cladded by polymer modified cement-based composite materials is made into modified beads,and thermal insulation blocks are made out through adding modified beads to cement mortar.The water absorption,thermal conductivity and compressive strength of modified beads are tested,and polymer cement ratio is determined.The density,thermal conductivity,water absorption and changes in intensity of the thermal insulation blocks with different proportions of modified beads are studied,and the linear regression analysis between mixing ratio and thermal conductivity is carried out.
