Sample Preparation for Compression Test

For the MH project EKS-92g and 127g batches were sintered earlier and they had to be prepared for the compression test. Since the clay content is somewhat higher the almost all the samples seem to be cracked. So I selected the samples carefully for preparation and cut them into 22.5 mm pieces which have to be reduced and smoothed to 20 mm according to the German standard.

Another kneading of Arg. body was done without fibers for five hours. The cleaning took about 3 hours as before and it is really a long and unhappy process since the two screws of the kneader can not be taken out of the machine. Reaching corners which have to be really cleaned was a painful process.
