The determination of mortar load capacity in masonry in situ is not an established technique. An indirect method is described in this paper and, like the earlier one by Gucci, N. and Moretti, A., Boll. Ingegneri Toscana No. 9 (1989), is based on the measurement of the amount of energy required to drill a small cavity in a mortar layer. The instrumentation, designed and built for this purpose, has been the subject of an experimental study aimed at setting up the parameters of measurement and finding the correlation between the drilling work and the mortar compressive strength. The results obtained are reported and discussed, and a first theoretical interpretation is given.

Abstract
The determination of mortar load capacity in masonry in situ is not an established technique. An indirect method is described in this paper and, like the earlier one by Gucci, N. and Moretti, A., Boll. Ingegneri Toscana No. 9 (1989), is based on the measurement of the amount of energy required to drill a small cavity in a mortar layer. The instrumentation, designed and built for this purpose, has been the subject of an experimental study aimed at setting up the parameters of measurement and finding the correlation between the drilling work and the mortar compressive strength. The results obtained are reported and discussed, and a first theoretical interpretation is given.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
