Abstract
a presente invenção refere-se a método para determinar um parâmetro de plasticidade de uma pasta de cimento hidratada compreendendo: fornecer componentes de uma pasta de cimento, misturar os componentes para obter uma pasta de cimento e despejar a dita pasta de cimento em uma célula oedométrica selada, realizar uma operação de medição oedométrica dentro de um intervalo de tempo de idade precoce predefinido após a misturação da dita pasta de cimento aplicando um caminho de tensão axial predefinido à pasta de cimento dentro da célula oedométrica durante uma duração de medição predefinida e medir uma deformação axial da pasta de cimento dentro da dita duração de medição predefinida. um parâmetro de plasticidade da pasta de cimento hidratada é determinado por uma operação de calibração compreendendo fornecer um valor inicial de um parâmetro de plasticidade de um modelo elastoplástico de pasta de cimento hidratada, determinando valores de deformação axial simulada resolvendo o modelo elastoplástico de cimento hidratado e comparando o valores de deformação axial simulada com as medições de deformação axial da pasta de cimento para determinar um parâmetro de plasticidade da pasta de cimento hidratada.
