Thermal homogenization of lightweight concrete using mean field micromechanical models

Palavras-chave: Micromecânica, homogeneização, concreto.

Resumo

Os modelos micromecânicos de campos médios são amplamente utilizados para a homogeneização de materiais heterogêneos com inclusões randômicas. O avanço da teoria da inclusão equivalente permitiu a determinação das propriedades físicas efetivas para diversos materiais compósitos. Com as propriedades de suas fases e as equações dos modelos propostos, pode-se realizar a homogeneização para a verificação com resultados experimentais. Este trabalho demonstra a obtenção das propriedades térmicas para aplicação na construção do concreto leve. Verifica-se que, com uma boa caracterização experimental das fases, é possível dispor de resultados analíticos que possibilitam um procedimento de escolha do percentual de inclusões no concreto, considerando a massa específica requerida e o desempenho térmico do material.
