新型砌筑用保温砂浆的研制

论述了保温砂浆的抗裂、增强机理。研制出一种新型砌筑用的保温砂浆。研究结果表明 ,纤维对砂浆存在着阻裂增强作用 ;对于同一种砂而言 ,有一个最适合掺加引气剂、改变孔结构的颗粒级配 ;砂浆有一个合理的引气量 ;适量的高分子水泥增强剂对提高砂浆强度有很大帮助 ,但掺量过多对强度的贡献不大

Development of New - type Insulation Mortar for Construction

Here is a discussion on the mechanism of cracking resistance and strengthening performance of the thermal insulation mortar.It is told here that a new-type mortar for masonry has been developed.The result of its study indicates that fibers have a crack- resisting and strengthening effect on mortar,that for the same sand there is a size distribution that best suits the mix of air-entraining and the change of pore structure,that there is a reasonable entrained air content for mortar,that a suitable amount of high-molecular cement intensifier is of great help to the improvement of mortar strength,though excessive amount of admixture has little help to it.
