Abstract

Results of optical microscopy, mortar bar expansion tests at 38 and 60 c and rapid chemical tests on quartzitic and granitic aggregates containing strained quartz are summarised. Limits are suggested for acceptable expansion in mortar bar tests at 60 c regime and the percentage of quartz showing strain effect and angle of undulatory extinction.(a) for the covering abstract of the conference see IRRD 811982.
