摘　　要：探讨了养护剂DPS对混凝土耐久性能的影响,并与普通混凝土进行了对比。结果表明:喷涂养护剂DPS以后,混凝土的抗渗性能、抗冻性能、抗氯离子渗透性能和抗碳化性能均有所提高,混凝土薄板微裂纹也大大减少。工程应用一年后,混凝土的抗渗性能和抗碳化性能仍强于未施用DPS的混凝土50%以上。Discusses the curing agents DPS on the properties of concrete durability,and then compared with the ordinary concrete.The results show that after coating the curing agent DPS,the permeability resistance,frost resistance,resistance to chloride ion permeability and carbonation resistance of concrete performance are improved,micro cracks concrete sheet also greatly reduced.The permeability resistance and carbonation resistance of concrete performance is still better than not more than 50%of the application of DPS concrete that after a year of engineering application.
