Abstract

"PASTA DE CIMENTO". Trata-se de uma pasta de cimento com uma densidade entre 750 kg/m^ 3^ e 1.000 kg /m^ 3^ compreendendo uma fração sólida que compreende: alternativamente 75% - 90% (por volume) de partículas leves com um tamanho médio de partícula entre 10 e 60 <109>m; 10% - 25% (por volume) de cimento Portland com um tamanho médio de partícula entre 10 e 50 <109>m, ou microcimento com um tamanho médio de partícula entre 0,5 e 5 <109>m; ou: 20% - 50% (por volume) de partículas leves com um tamanho médio de partícula entre 10 e 60 <109>m, 10% - 25% (por volume) de cimento Portland com um tamanho médio de partícula entre 10 e 50 <109>m ou microcimento com um tamanho médio de partícula entre 0, 5 e 5 <109>m; 35% - 65% (por volume) de partículas leves com um tamanho médio de partícula entre 100 e 200 <109>m; e uma fração líquida presente em uma quantidade de 37% - 50% (por volume) do volume total. Esses cimentos possuem notáveis propriedades mecânicas devido a sua porosidade muito baixa apesar de possuírem uma densidade muito baixa.
