A slump test apparatus is a device that is used to measure the workability and consistency of freshly made concrete that is to be used for construction purposes. In layman's term, this test apparatus measures the ease with which concrete flows and also the degree of it's moisture content.
The test apparatus generally consists of one slump cone, a base plate, handles and foot pieces. The foot pieces are fixed to the clamps on the base plate. The base plate also consists of a lifting handle for easier handling and transportation purposes. The slump test apparatus has been widely used for over 50 years in order to maintain quality of fresh concrete that is to be delivered to a construction site. Available at industry leading rates, these are available in both standard and customized technical specifications.
Factors To Keep in Mind While Buying a Slump Test Apparatus :
The slump cone of the apparatus should be made of galvanized iron sheet or any other suitable metal
The top and bottom of the slump cone should be open and parallel to each other
The thickness of the slump cone should be at least 1.6 mm
The internal surface of the slump test apparatus should be smooth and free from any dents and protruding rivets.
Applications of Slump Test Apparatus
The slump test apparatus is used to ensure uniformity for different batches of similar concrete under natural field conditions.
The slump test apparatus is widely used at construction sites to periodically check variations in the materials being fed into the mixture
The apparatus is also used to check for any deficiency of sand in the concrete paste
To check if the concrete slump is too high or too low, thus providing optimal time to remedy the situation in either case.
Different Global Standards for The Dimensions and Usage Process of The Slump Test Apparatus
The slump test apparatus is widely used in construction facilities across all continents. However , some differences in regulations specifying the dimensions and usage patterns of the slump test apparatus are common.
To illustrate, in the united states, regulations specifically state that the dimensions of the slump cone should be 12 inches in height, an upper diameter of 4 inches and a bottom diameter of 8 inches. Meanwhile, European standards state that the dimensions of the slump cone of slump test apparatus should be 300 mm in height, an upper diameter of 100mm and bottom diameter of 200 mm. Also, in the united states , it is mandated that slump cone should only be lifted vertically during the removal process. As for Europe no such regulations exist.
