摘　　要：对比分析多种养护方式对机制砂混凝土性能的影响,发现采用棉絮养护的混凝土构件表面强度最高,其次是采用养护膜养护的混凝土构件;各种养护方式下混凝土电通量值由高到低排序:标准养护>棉絮养护>土工布养护>养护膜养护>养护剂养护>塑料薄膜养护>自然养护,基本处于一个等级,属于低氯离子渗透性;干缩变形值由大到小排序:标准养护>塑料薄膜养护>棉絮养护>土工布养护>养护膜养护>自然养护>养护剂养护。This article compares and analyzes the effects of various curing methods on the performance of machinemade sand concrete.It is found that the surface strength of concrete components cured with cotton wool is the highest,followed by those cured with curing film.The electrical flux values of concrete under various curing methods,from high to low,are as follows that standard curing>cotton wool curing>geotextile curing>curing film curing>curing agent curing>plastic film curing>natural curing,which are basically at the same level and belong to low chloride ion permeability.The order of shrinkage deformation values from large to small is that standard curing>plastic film curing>cotton wool curing>geotextile curing>curing film curing>natural curing>curing agent curing.

关 键 词：机制砂混凝土 养护方式 耐久性能 干缩变形
