摘要
含气量对混凝土性能的影响是多面而又复杂的,含气量对混凝土的和易性、抗折强度、耐磨性能、抗冻性能、抗渗透性能、热传导性能、自身变形等性能有明显的影响,适宜的含气量有利于增强混凝土的综合性能。然而,含气量也会在一定程度上造成混凝土强度的损失,合理适宜的含气量才能使混凝土的综合性能得到有效改善。
Air content on the properties of concrete is multi-faceted and complex.The air content has a significant impact on the concrete's workability,flexural strength,wear resistance,frost resistance,anti-permeability,thermal conductivity,its deformation properties.Appropriate air content enhances the overall performance of concrete.However,the air content can also result in the loss of concrete strength.The overall performance of the concrete can only be effectively improved when the appropriate amounts of air is introduced.
