Bond strength of masonry joints under normal pressure while curing
University of New Brunswick
In order to examine the effects of normal pressure on tensile bond strength during mortar curing, test specimens were cured under varying pressures. A total of 44 concrete block specimens were tested in flexure. These were cured under pressures of zero, two, four, six, and eight blocks. The time of load placement was also varied using zero, ten , and twenty mi nutes. Bond strength was found to increase with increased pressure„ Th is eff ect di mi n i shes with i ncreased ti me of I oad pIacement.
