摘　　要：通过研究影响保温砂浆收缩开裂的因素,对影响程度进行对比,比较采用养护和无养护泵送保温砂浆的收缩率的差异,不同胶集比的保温砂浆的开裂情况,不同保水剂的添加对保温砂浆开裂情况的影响,用相应规律对保温砂浆的开裂情况进行抑制.Through analyzing different factors affecting insulation mortar shrinkage cracking,the degree of influence was compared.The shrinkage difference between maintenance and non-maintenance insulation mortar,the crack situation of super absorbent polymers with insulation mortar of different rubber sets,and the influence of different insulation mortar added on the crack situation were compared with corresponding law of insulation mortar undertake inhibition of crack situation.
