<DIV>Brittle matrix composites are applied in various domains (such as civil engineering, mechanical equipment and machinery and vehicles) and in the last few decades, their importance is increasing together with their variety.<br><BR>These are the conference proceedings for the 10th International Symposium on Brittle Matrix Composites, held October 2012 in Warsaw, Poland, sponsored by the IFTF of the Polish Academy of Sciences. The papers of the Symposia are on composite materials with matrixes behaving as brittle in normal or special conditions and cover aggregate-binder composites, sintered materials and high strength composites with brittle matrixes. The conference papers also cover material engineering problems such as: design and optimization of the structure of materials, theoretical considerations and computational methods, models of materials and prediction of material properties, test methods and new test results, manufacturing processes, applications of new materials and their behavior in service and durability assessments and environmental effects. <br><BR><BR></div>
