Fine Aggregate Stone Powder Content Testing Instrument for 细骨料石粉含量测试仪

This instrument is a special instrument designed according to T0349-2005 of Ministry of transportation, "fine aggregate methyleneblue test".
Advanced frequency modulation, numerical control technology are adopted to improve the test accuracy and speed. It is a necessary instrument for the laboratory. This method is suitable for determining whether there are expansive clay minerals in fine aggregate
and its content, so as to evaluate the cleanliness of aggregates, expressed as methylene blue value MBV. This method is suitable for fine aggregate less than 2.36mm or less than 0.15mm, and also can be used for quality inspection of mineral powder.
If the passing rate of 0.075mm in fine aggregate is less than 3%, it can be regarded as qualified without this test.

本仪器是根据交通运输部T0349-2005《细骨料亚甲蓝试验》设计的专用仪器。

采用先进的调频、数控技术，提高了测试精度和速度。这是实验室必备的仪器。该方法适用于确定细骨料中是否存在膨胀粘土矿物

以评估聚集体的清洁度，以亚甲基蓝值MBV表示。该方法适用于小于2.36mm或小于0.15mm的细骨料，也可用于矿粉的质量检验。

如果细骨料中0.075mm的合格率小于3%，则可认为未经本试验合格。
