摘要
试验分别研究了新老混凝土黏结试件在水泥净浆界面剂和新型改性环氧界面剂作用下的抗冻性能与抗水渗透性能,分析了不同界面剂对黏结抗冻性能及抗水渗透性能的影响变化规律和机理。结果表明:涂刷新型改性环氧界面剂的新老混凝土黏结试件的抗冻性能和抗水渗透性能均优于使用水泥净浆界面剂的新老混凝土黏结试件。
The frost resistance and water permeability resistance of new and old concrete bonding specimens under the action of cement paste interface agent and new modified epoxy interface agent are studied respectively,and the effects and mechanism of different interfacial agents on the frost resistance and water permeability resistance of bonding are analyzed.The results show that the frost resistance and water permeability resistance of the new and old concrete bonded specimens coated with new modified epoxy surface agent are better than those of new and old concrete bonded specimens with cement paste interface agent.
