eVB(expanded and vitrified small ball)保温砂浆具有导热系数低、保温隔热性能好、防火等级高、黏结性能好、施工方便、环保无毒等特点,非常适用于夏热冬暖(冷)地区的外墙隔热保温。本文通过具体试验数据比较分析在eVB保温砂浆内添加适量的聚乙烯醇纤维后对导热系数、干密度、抗压强度、抗折强度、软化系数等的影响,探讨更优的节能环保材料,以抛砖引玉。
eVB (expanded and vitrified small ball) thermal insulation mortar with low thermal conductivity, good thermal insulation properties, high fire rating, good bonding performance, easy construction, environmental protection and other non-toxic, is very suitable for the hot summer and warm winter Exterior insulation. In this paper, comparative analysis of the specific experimental data in the eVB thermal insulation mortar after adding appropriate amount of polyvinyl alcohol fibers on the thermal conductivity, dry density, compressive strength, flexural strength, softening coefficient, to explore better energy-saving environmental protection materials to Initiate
