▶The test apparatus is carried out by filling the slump cone with freshly mixed concrete which is tamped with a steel rod in three layers. The concrete is leveled off with the top of the slump cone, the cone removed, and the slump of the sample is immediately measured. We propose two different models: the standard one particularly suitable for laboratory testing and the portable model very practical for site testing shown as below. Each component of the kits can be ordered separately. The user can personalize the kit composition for the slump cone test
