利用红外线辐射加热来养护混凝土,是近几年来国内试用的一项新技术。它为缩短混凝土预制构件的养护周期,加速设备及场地周转,提高产品质量和劳动生产率开辟了新途径,是一种很有前途的养护工艺。两年来,我们采用液化石油气红外线对混凝土进行辐射养护,作了一系列试验,并初步在室 The use of infrared radiation heating to preserve concrete is a new technology that has been tested in China in recent years. It opens up new ways for shortening the maintenance cycle of concrete prefabricated components, accelerating equipment and site turnover, and improving product quality and labor productivity. It is a very promising maintenance process. In the past two years, we have used liquefied petroleum gas infrared radiation curing of concrete and made a series of tests.
