The unit VIKA IV-2 is designed to determine the normal density, timing, setting and determining the thickness of crust of cement grout. Thickening time of cement grout or mortar component is determined from data on setting time. The characteristics of this process is the time to start setting time and setting to the end. When the cement slurry reaches the state corresponding to the beginning of setting, it can not be properly packed and sealed. Final set corresponds to the onset of hardening test.
Since the beginning of setting concrete mix undergoes a significant loss of yield. In the concrete mixture is also observed a false setting. It notably in cases where the curing occurs in the presence of partially dehydrated gypsum. Udo-boukladyvaemost mixture can not recover the additional mixing. The false setting may be due to the formation of excessive amounts of ettringita – especially in the presence of some inhibitors. Needle VIKA IV-2 is designed to determine the normal density, timing, setting and determining the thickness of the cement crusts test.
In this method, the time to start setting is fixed when the needle goes into the dough to a depth of 25 mm and the time before the end of the setting – when the needle does not penetrate much into cement paste. Specifications: Diameter of needle, mm: 1,1 0,04 Needle length, mm: 50 Diameter of the pistil, mm: 10 0,02 length of pistil, mm: 60 Weight moving rod with a needle or a pestle, g: 300 2 Scale, mm: 1 Height ring to cement paste, mm: 40 0,5 Overall dimensions: 140h160h245 The following accessories are includes: unit Vick IV-2 in the assembly manual.
