In our experience, the tabs feature of a “classic” slump plate all too easily get covered up in concrete to the point of ceasing to function. Here at Kuka Sale Group, we feel that there’s no need to pay for such a feature when it’s practicality and usefulness are so short-lived.
Tabs are not ultimately needed to hold down the slump cone, when simply standing on the cone will suffice for the duration of a slump test. For a similar reason, our slump plates don’t have a typical handle, but rather just a “hand hold” so that regardless of concrete build up, you’ll always be able to pick it up with ease.
