水泥浆稠度测定仪
一、概述：水泥是采用硅酸盐水泥或普通水泥，采用矿渣水泥时，应加强检查，以防止材性不稳定。水泥的标号不宜低于425号。
水泥浆稠度宜控制在14-18S之间，稠度的测定采用1725ml漏斗试验，水泥浆稠度测定仪生产厂家规格质优水泥浆从漏斗流出的时间（S），即为水泥浆的稠度。水泥浆面位置可用灌入1725ml水的方法找出。用点测规标记。

三、设备流动锥：出料管应用不锈钢制作，锥体可用铸铝或其他非腐蚀性材料制作。
注：只要能获得水泥（砂）浆浆面的精确值，可以使用其他的指示装置。接受容器：最小容量为2000ml环架或其他装置：保持接受容器上方流动锥位置垂直和稳定的装置。水平尺：木工使用的或类似的水平尺秒表：最小读数应不大于0.1s。试验设备校准：流动锥应以无振动的方式安装牢固。
