Abstract

Interventions historic brick buildings require an exhaustive analysis of the current characteristics of the bricks, in order to establish the role that these elements maintain in the buildings. This study presents the result of an experimental analysis for the compressive strength of brick specimens extracted from different buildings built in the 19th and 20th centuries in the province of Zamora (Spain). specimens with very different characteristics are analysed, allowing comparisons between brickworks and manufacturing processes. The obtained resistance values are related to the result of a macroscopic and microscopic analysis of the material, which classifies the pieces into four groups, and to the results of the study of the density, absorption and open porosity of the samples. The compressive strength results show high variation between brick specimens and in-between the samples extracted from the same brick. A correlation between the of resistance and open porosity values, with less dispersion in the case of high sintering level is observed. Finally, the compliance with the current rules respect to their carrying capacity is checked.
