Evaluation of binder VST-1210 with different curing modes by sclerometry methods
Cured samples from the binder VST-1210 with the help of a laboratory sclerometer were applied to scratches under various loads on the diamond indenter, after which the character of the formed grooves and their geometry were studied. It has been established that the microhardness of the samples and the nature of the grooves depend on the modes of curing the binder. The applied method of sclerometry made it possible to determine the curing regimes of the samples in which, after the action of the indenter, the plastic is cracked, or the chevron character of the channel of the groove, indicating a low degree curing.
