新浇混凝土如不采取加热措施,则硬化时间多数会长达4天;在+5℃以下,如不加热,硬化过程一般来说便不能进行。因此多年来,在混凝土预制构件生产方面采取了加热措施,并且在许多混凝土预制构件厂中得到证实,利用煤气红外线辐射器来采暖,不仅是经济而适宜的采暖措施,并能大大缩短混凝土的硬化时间。用煤气红外线辐射器采暖,使室内工作人员在冷天有着舒适的室温,下班后辐射器也不关闭。在夜间,车间内所有的辐射器还要自动地开几小时,并且 If fresh concrete is not heated, the hardening time will last for up to 4 days. Below +5°C, if it is not heated, the hardening process cannot generally be carried out. Therefore, over the years, heating measures have been taken in the production of prefabricated concrete components, and it has been confirmed in many prefabricated concrete structures. The use of gas infrared radiators for heating is not only an economical and appropriate heating measure, but also can greatly reduce the hardening of concrete. time. The use of gas infrared radiator heating, so that indoor staff have a comfortable room temperature in the cold, the radiator does not turn off after work. At night, all radiators in the workshop are automatically opened for hours, and
