加拿大创制了一种新的坍落度测定器,称谓“托拉姆”(TORAM),如图1所示。这是一种直读式测定器(呈圆筒形,60毫米×300毫米),与以往的坍落度测定器相比,操作是非常简单的,测定时间约一分钟。这个仪器还可测试混凝土的和易性。
Canada created a new slump measuring device called “TORAM” (Figure 1). This is a direct-reading type measuring device (cylindrical, 60 mm x 300 mm), and its operation is very simple compared with the conventional slump measuring device. The measuring time is about one minute. This instrument also tests the workability of concrete.
