摘 要:為了明確水泥基滲透結晶型防水劑對水泥基材料自修復性能的影響,研究了防水劑摻量為0、1%、2%、3%時砂漿試塊裂縫的自愈合過程,并利用XRD、SEM、FT-IR等手段分析了防水劑中的活性物質以及自修復產物的主要成分、晶相和微觀形貌,提出了其對水泥基材料自修復作用機理,對其在工程中的應用以及國內自主研發該類產品具有一定的借鑒作用。
Abstract: In order to clarify the effect of cementitious capillary crystalline waterproofing admixture on the self-healing performance of cementitious materials, the self-healing process of cracks in mortar samples was studied when the amount of waterproofing admixture was 0, 1%, 2% and 3%. Furthermore, XRD, SEM, FT-IR and other characterization methods were used to analyze the main components of the activated chemical additive in the cementitious capillary crystalline waterproofing admixture, crystal phases and micro-morphologies of self-healing products were aslo investigated. Finally, the self-healing mechanism of the materials was proposed, which had a certain reference to the applications and domestic research of such products.
