众所周知,引气剂是能够显著提高混凝土耐久性的一种外加剂。以前称做“加气剂”。但根据国际标准化组织(ISO)关于“混凝土、砂浆及灌注用净浆外加剂的定义及分类”中规定,引气剂与加气剂是两种不同类型的外加剂,前者指“能在混凝土或砂浆中形成细小的、均匀分布的并、在硬化后仍能保持空气微泡的外加剂”,而后者是指 As we all know, air-entraining agent can significantly improve the durability of concrete admixture. Previously known as “air entraining agent.” However, according to the provisions of the International Organization for Standardization (ISO) on the definition and classification of clear concrete admixtures for concrete, mortar and grouting, air-entraining and aerating agents are two different types of admixtures. The former refers to “ Or mortar to form fine, evenly distributed and, after curing can still maintain the air microbubbles admixture ”, while the latter refers to
