Influência do tipo de agregado na resistência e deformabilidade de blocos estruturais produzidos com concreto seco: estudo numérico, experimental e estatístico

Abstract: RESUMO O comportamento da alvenaria estrutural resulta do desempenho de cada componente: unidades, juntas de argamassa, grautes e armaduras. Comercialmente, os blocos para alvenaria são produzidos com concreto seco ou zero-slump. Sua dosagem e propriedades físicas se diferem consideravelmente dos concretos convencionais e dependem da eficiência de compactação das máquinas vibroprensas. Ensaiar elementos de alvenaria em tamanho natural é dispendioso e requer uma infraestrutura específica. Nessa perspectiva, mod… Show more

“…Some studies on the effects of high temperatures on masonry structures have been developed over the last decades and reviewed by some authors [9][10][11]. Other works have focused on investigations of masonry components (e.g., units, mortar, and grout) exposed to elevated temperatures [12][13][14][15][16][17][18]. Despite this, scarce information is still available that provides quantitative data regarding the effects of fire on the structural performance of masonry elements.…”
