在港口建设中,为了控制混凝土配合比,需要测定砂的含水率。测定砂的含水率有烘箱烘干的标准测定法,电炉炒干、酒精燃烧快速测定法。但这三种方法都存在一定缺点,如需专门设备,耗电或酒精,时间较长等。为了改进测定方法,我们研制成功了“浮称法砂含水率快速测定仪”,现简介如下。 In the construction of the port, in order to control the concrete mix ratio, the moisture content of the sand needs to be measured. The determination of the moisture content of the sand oven oven drying standard method, electric stove frying, rapid determination of alcohol burning. However, these three methods all have certain drawbacks, such as the need for specialized equipment, power consumption or alcohol, and a long time. In order to improve the measurement method, we have successfully developed the “fast measurement method for water content of float sand”, which is summarized as follows.
