混凝土外加剂的技术经济效益

THE TECHNIC-ECONOMIC EFFECT OF ADDING AN ADDITIVE AGENT INTO THE CONCRETE

在混凝土中使用外加剂是目前混凝土科学技术发展的一个重要方向。但是，我国在混凝土外加剂的研究、生产和使用上与工业发达国家相比还有很大差距。文章分析了外加剂在节约水泥、节约能源、提高混凝土强度、改善混凝土耐久性、提高劳动效率和产量、改善施工条件等方面的技术经济效益，以期引起人们对外加剂的重视。

It is a trend in the development of science and technology of the concrete work to add some additive agent into the cement concrete. The research, production and application, however, on the cement additive agent in China are far behind the developed countries, the economy in cement and in energy and improvement of the strength, lifetime of the concrete as well as the work conditions by using the additive agent are analysed in order to cause people's attention on the use of cement additive agent.
