Statistical Peculiar Features of Surface Cracking on Flat Clay Samples of Plastic Moulding when Heated by Heat Flow

Results of 240 time determinations pertaining to investigation of surface cracking initiation on flat samples of moulding mass (80% of the Lukoml clay + 20% of granite screenings) of various thickness (1 ...4 cm) while being heated with intensive heat flow (~ 1 W/cm2) are given and analyzed in the p...

Description
Summary:Results of 240 time determinations pertaining to investigation of surface cracking initiation on flat samples of moulding mass (80% of the Lukoml clay + 20% of granite screenings) of various thickness (1 ...4 cm) while being heated with intensive heat flow (~ 1 W/cm2) are given and analyzed in the paper.It has been shown that under such heating conditions thickness of a sample practically does not make any effect on cracking intensity. At the same time determination of time indices concerning cracking initiation prior to clay mass treatment in the vacuum-press in accordance with K.Pirson’s criterion does not correspond to the normal law of distribution of random indices and corresponds to this law after processing in vacuum-press and moulding of air-dried bricks that makes it possible to predict with great reliability an output of qualitative products.
