【摘要】 混凝土建筑物的裂缝会在不同程度上影响其功能。XYPEX水泥基渗透结晶型防水材料由于其良好的自愈合性能和防水性能而应用于混凝土裂缝修复。通过试验分析了XYPEX对不同龄期混凝土开裂的修复性能,借助扫描电镜和能谱仪进行观察分析不同养护条件及裂缝宽度对修复效果的影响。试验表明:潮湿和水分充足的养护条件对混凝土裂缝修复更有利;缝宽较大时,生成物的尺寸越大,数量越多;XYPEX对砂浆裂缝面的处理对裂缝起到了有效的修复作用。更多还原

【Abstract】 Cracks in concrete structures will affect the features in varying degrees.XYPEX cementitious capillary crystalline waterproofing material has been used in concrete crack repair as its good self-healing property and waterproof performance.The experiment in this paper analysised the performance of XYPEX on repairing cracks of concrete in diffrent ages,and the effect of different curing conditions and crack width by SEM and EDS.The experiment shows that the high curing humidity is more favorable to the concrete crack repair.When the crack width is larger,the size and the number of the product are larger.The processing of the XYPEX on the surface of the mortar cracks plays an effective role on cracks repair.更多还原
