摘要
随着我国市场经济的快速发展,建筑工程也是在不断的增加,而混凝土作为建筑行业中最主要的工程材料之一,也得到了广泛的应用。混凝土在成型的过程中会形成一定的有害气泡和有益气泡,因此我们需要通过一些技术手段来减少有害气泡的存在,增加有益气泡的数量,改善混凝土的性能。概述了引气剂、消泡剂以及发泡剂3种混凝土气泡调控外加剂的现状及发展情况,并且介绍了3种外加剂的分类、组成及特点,以及它们的发展趋势。
With the rapid development of China′s market economy,and increasing construction engineering,concrete has been widely used,that as one of the most important engineering materials in the construction industry.Harmful and beneficial bubbles were formed in the process of concrete forming,therefore,it need improve the performance of concrete by reducing the number of harmful bubbles,and increasing the number of beneficial bubbles.It introduced the current situation and development of air-entraining agent,defoamer and foaming agent,that as bubble controlled admixtures in concrete,and their classification,composition,characteristics and development trend.
