For the determination of the slump value of cement slurry.
The dry tube is placed on the target plate coincident with the innermost ring and is then completely filled with the slurry under test. Care must be taken to expel any air bubbles, if necessary, by gently rodding the mix. The tube is then lifted vertically off the plate thereby allowing the slurry to flow over the target area of concentric circles. The slump value is given by the extent of flow of the slurry and is expressed on the scale 0-8.
Three tests are carried out and the results should agree
