Joanna Misiewicz, Maria Tunkiewicz, Gergő Ballai, Ákos Kukovecz

TL;DR
This study analyzes historical bricks from Baroque monuments in Poland to understand their properties and guide restoration efforts.
Contribution
The study systematically characterizes historical bricks and evaluates compatibility with modern repair materials for conservation.
Findings
Pore size ranges most vulnerable to frost damage were identified in historical bricks.
Correlations between physical, hygric, and mechanical properties of the bricks were revealed.
Results provide data to inform the selection of compatible materials for conservation.
Abstract
This study presents a comprehensive material characterization, including physical, hygric, and mechanical properties, of historical ceramic bricks to enhance the understanding of heritage masonry structures and support the effective planning of conservation interventions. The primary objective is to systematize the knowledge of constituent materials in brick walls from different historical periods and to evaluate the compatibility of modern repair materials with the original fabric. To this end, a comprehensive experimental protocol was employed, which included the determination of fundamental physical properties such as density, water absorption, and sorptivity. Additionally, chemical and thermogravimetric analyses were performed, followed by freeze–thaw resistance testing and compressive strength measurements. Microstructural analysis was conducted using mercury intrusion porosimetry.…
