一、引气剂属水泡组分,纯物理性能,搅拌水泥浆过程中投入,形成小小的空气泡。这些气泡不消失,在硬化的混凝土中分部成微小的孔隙。其作用是提高混凝土的抗冻融性能,改善混凝土稳定性。通常,引气剂的用量占水泥重量的0.03～0.05%,有少量的塑化作用,可节约用水量的5～8%。 First, the air-entraining agent is a blistering component, pure physical properties, and the process of mixing cement slurry to input, forming a small air bubble. These bubbles do not disappear and they divide into tiny pores in hardened concrete. Its role is to improve the freeze-thaw resistance of concrete and improve the stability of concrete. In general, the amount of air-entraining agent accounts for 0.03 to 0.05% of the weight of cement, and there is a small amount of plasticization, which can save 5 to 8% of the water.
