英国水泥与混凝土协会研制成功一种快速测定混凝土中水泥含量的新设备(图1),据称其测定时间只要10分钟,该设备装在实验室或汽车拖车上,便于现场使用,可供在混凝土浇灌或搅拌车出料之前就纠正水泥用量差错,以防止质量不合格的问题。
A new device for rapid determination of cement content in concrete has been developed by the British Cement and Concrete Association (Fig. 1). It is said that the measurement time is only 10 minutes. The device is installed in a laboratory or car trailer and is convenient for on-site use. Before the concrete is poured or the mixer truck discharges, the cement usage error is corrected to prevent the quality from being unqualified.
