一、概述 为了加强混凝土的质量控制,确保预制构件的质量,随时掌握混凝土的变化动态,及时调整混凝土配合比,我们于1983年初采用远红外养护箱设备快速测定混凝土强度,进行现场混凝土质量控制。 远红外养护箱,由于采用了近几年来发展起来的远红外加热新技术,配备了热敏电阻控温测温仪,具有快速、低耗、调节方便等优 First, an overview In order to strengthen the quality control of concrete to ensure the quality of prefabricated components, keep abreast of changes in concrete dynamics, timely adjustment of concrete mix, we used far infrared curing box equipment in early 1983 rapid determination of concrete strength, on-site concrete quality control. Far-infrared curing box, due to the use of the recent years developed far-infrared heating technology, equipped with a thermistor temperature thermometer, with fast, low consumption, easy adjustment and other advantages
